Virtual Private Routed Network service
This chapter provides information about the Virtual Private Routed Network (VPN) service and implementation notes. VPRN services are supported only in network mode.
VPRN service overview
RFC2547b is an extension to the original RFC 2547, which details a method of distributing routing information and forwarding data to provide a Layer 3 Virtual Private Network (VPN) service to end customers.
Each Virtual Private Routed Network (VPRN) consists of a set of customer sites connected to one or more PE routers. Each associated PE router maintains a separate IP forwarding table for each VPRN. Additionally, the PE routers exchange the routing information configured or learned from all customer sites via MP-BGP peering. Each route exchanged via the MP-BGP protocol includes a Route Distinguisher (RD), which identifies the VPRN association.
The service provider uses BGP to exchange the routes of a particular VPN among the PE routers that are attached to that VPN. This is done in a way which ensures that routes from different VPNs remain distinct and separate, even if two VPNs have an overlapping address space. The PE routers distribute routes from other CE routers in that VPN to the CE routers in a particular VPN. Because the CE routers do not peer with each other, there is no overlay visible to the VPN routing algorithm.
When BGP distributes a VPN route, it also distributes an MPLS label for that route. On a SR-Series, the label distributed with a VPN route depends on the configured label-mode of the VPRN that is originating the route.
Before a customer data packet travels across the service provider's backbone, it is encapsulated with the MPLS label that corresponds, in the customer's VPN, to the route which best matches the packet's destination address. The MPLS packet is further encapsulated with either another MPLS label header, so that it gets tunneled across the backbone to the correct PE router. Each route exchanged by the MP-BGP protocol includes a route distinguisher (RD), which identifies the VPRN association. Therefore the backbone core routers do not need to know the VPN routes. The following figure shows a VPRN network diagram example.
Routing prerequisites
RFC2547bis requires the following features:
Multi-protocol extensions
Extended BGP community support
BGP capability negotiation
Parameters defined in RFC 2918
Tunneling protocol options are as follows:
Label Distribution Protocol (LDP)
MPLS RSVP-TE tunnels
BGP support
BGP is used with BGP extensions mentioned in Routing prerequisites to distribute VPRN routing information across the service provider network.
BGP was initially designed to distribute IPv4 routing information. Therefore, multi-protocol extensions and the use of a VPN-IPv4 address were created to extend ability of the BGP to carry overlapping routing information. A VPN-IPv4 address is a 12-byte value consisting of the 8-byte route distinguisher (RD) and the 4-byte IPv4 IP address prefix. The RD must be unique within the scope of the VPRN. This allows the IP address prefixes within different VRFs to overlap.
A VPN-IPv6 address is a 24-byte value consisting of the 8-byte RD and 16-byte IPv6 address prefix. Service providers typically assign one or a small number of RDs per VPN service network-wide.
Route distinguishers
The route distinguisher (RD) is an 8-byte value consisting of 2 major fields, the Type field and Value field, as shown in the following figure. The Type field determines how the Value field should be interpreted. The 7210 SAS implementation supports the three (3) Type values as defined in the Internet draft.
The three Type values are:
Type 0: Value Field - Administrator subfield (2 bytes) Assigned number subfield (4 bytes)
The administrator field must contain an ASN (using private AS numbers is discouraged). The Assigned field contains a number assigned by the service provider.
Type 1: Value Field - Administrator subfield (4 bytes) Assigned number subfield (2 bytes)
The administrator field must contain an IP address (using private IP address space is discouraged). The Assigned field contains a number assigned by the service provider.
Type 2: Value Field - Administrator subfield (4 bytes) Assigned number subfield (2 bytes)
The administrator field must contain a 4-byte ASN (using private AS numbers is discouraged). The Assigned field contains a number assigned by the service provider.
Route reflector
Per RFC2547bis the use of Route Reflectors is supported in the service provider core. Multiple sets of route reflectors can be used for different types of BGP routes, including IPv4 and VPN-IPv6. 7210 can only be used a route reflector client. It cannot be used as a route reflector ("server").
CE to PE route exchange
Routing information between the Customer Edge (CE) and Provider Edge (PE) can be exchanged by the following methods:
Static Routes (with both IPv4 and IPv6)
E-BGP (with both IPv4 and IPv6 VPNs)
Each protocol provides controls to limit the number of routes learned from each CE router.
Route redistribution
Routing information learned from the CE-to-PE routing protocols and configured static routes should be injected in the associated local VPN routing/forwarding (VRF). In the case of dynamic routing protocols, there may be protocol-specific route policies that modify or reject some routes before they are injected into the local VRF.
Route redistribution from the local VRF to CE-to-PE routing protocols is to be controlled via the route policies in each routing protocol instance, in the same manner that is used by the base router instance.
The advertisement or redistribution of routing information from the local VRF to or from the MP-BGP instance is specified per VRF and is controlled by VRF route target associations or by VRF route policies.
VPN-IP routes imported into a VPRN, have the protocol type bgp-vpn to denote that it is an VPRN route. This can be used within the route policy match criteria.
CPE connectivity check
Static routes are used within many IES and VPRN services. Unlike dynamic routing protocols, there is no way to change the state of routes based on availability information for the associated CPE. CPE connectivity check adds flexibility so that unavailable destinations are removed from the VPRN routing tables dynamically and minimize wasted bandwidth.
The following figures show static routes.
The availability of the far-end static route is monitored through periodic polling. The polling period is configured. If the poll fails a specified number of sequential polls, the static route is marked as inactive.
Either ICMP ping or unicast ARP mechanism can be used to test the connectivity. ICMP ping is preferred.
If the connectivity check fails and the static route is de-activated, the 7210 SAS router continues to send polls and reactivate any routes that are restored.
Constrained route distribution
This section describes constrained route distribution or RT constraint (RTC).
Constrained VPN route distribution based on route targets
The RTC is a mechanism allows a router to advertise route target membership information to its BGP peers to indicate interest in receiving only VPN routes tagged with specific route target extended communities. After receiving this information, peers restrict the advertised VPN routes to only those requested, which minimizes the control plane load in terms of protocol traffic and possibly routing information base (RIB) memory.
MP-BGP carries the route target membership information, using an address family identifier (AFI) value of 1 and subsequent address family identifier (SAFI) value of 132. For two routers to exchange RT membership network layer reachability information (NLRI), they must advertise the corresponding AFI/SAFI to each other during capability negotiation. MP-BGP allows RT membership NLRI to be propagated, loop-free, within an AS and between ASs using well-known BGP route selection and advertisement rules.
Outbound route filtering (ORF) can also be used for RT-based route filtering, but ORF messages have a limited scope of distribution (to direct peers or neighbors), and, therefore, do not automatically create pruned inter-cluster and inter-AS route distribution trees.
Configuring the route target address family
RTC is supported only by the base router BGP instance. When the family command at the bgp, group or neighbor CLI context includes the route-target keyword, the RTC capability is negotiated with the associated set of eBGP and iBGP peers.
ORF and RT C are mutually exclusive on a specific BGP session. The CLI does not attempt to block this configuration, but if both capabilities are enabled on a session, the ORF capability is not included in the OPEN message sent to the peer.
Originating RT constraint routes
When the base router has one or more RTC peers (BGP peers with which the RTC capability has been successfully negotiated), one RTC route is created for each RT extended community imported into a locally-configured Layer-2 VPN or Layer-3 VPN service. These imported route targets are configured in the following contexts:
config>service>vpls>bgp
config>service>vprn
config>service>vprn>mvpn
See the 7210 SAS-Mxp, R6, R12, S, Sx, T Routing Protocols Guide for more information about BGP address families that support RTC.
By default, these RTC routes are automatically advertised to all RTC peers, without the need for an export policy to explicitly accept them. Each RTC route has a prefix, prefix length, and path attributes. The prefix value is the concatenation of the origin AS (a 4-byte value representing the 2- or 4-octet AS of the originating router, as configured using the configure router autonomous-system command) and 0 or 16 to 64 bits of a route target extended community encoded in one of the following formats: 2-octet AS specific extended community, IPv4 address specific extended community, or 4-octet AS specific extended community.
A router may be configured to send the default RTC route to any RTC peer using the new default-route-target group or neighbor CLI command. The default RTC route is a special type of RTC route that has zero prefix length. Sending the default RTC route to a peer conveys a request to receive all VPN routes (regardless of route target extended community) from that peer. The default RTC route is typically advertised by a route reflector to its clients. The advertisement of the default RTC route to a peer does not suppress other, more specific, RTC routes from being sent to that peer.
Receiving and re-advertising RT constraint routes
All received RTC routes that are deemed valid are stored in the RIB-IN. An RTC route is considered invalid and treated as withdrawn if any of the following conditions apply:
The prefix length is 1 to 31.
The prefix length is 33 to 47.
The prefix length is 48 to 96 and the 16 most-significant bits are not 0x0002, 0x0102, or 0x0202.
If multiple RTC routes are received for the same prefix value, standard BGP best path selection procedures are used to determine the best of these routes.
The best RTC route per prefix is re-advertised to RTC peers based on the following rules:
The best path for a default RTC route (prefix length 0, origin AS only with prefix length 32, or origin AS plus 16 bits of an RT type with prefix length 48) is never propagated to another peer.
A PE with only iBGP RTC peers that is neither a route reflector nor an AS boundary router (ASBR) does not re-advertise the best RTC route to any RTC peer because of standard iBGP split horizon rules.
A route reflector that receives its best RTC route for a prefix from a client peer re-advertises that route (subject to export policies) to all of its client and non-client iBGP peers (including the originator), per standard RR operation. When the route is re-advertised to client peers, the RR sets the ORIGINATOR_ID to its own router ID and modifies the NEXT_HOP to be its local address for the sessions (for example, system IP).
A route reflector that receives its best RTC route for a prefix from a non-client peer re-advertises that route (subject to export policies) to all of its client peers, per standard RR operation. If the RR has a non-best path for the prefix from any of its clients, it advertises the best of the client-advertised paths to all non-client peers.
An ASBR that is neither a PE nor a route reflector that receives its best RTC route for a prefix from an iBGP peer re-advertises that route (subject to export policies) to its eBGP peers. It modifies the NEXT_HOP and AS_PATH of the re-advertised route per standard BGP rules. The aggregation of RTC routes is not supported.
An ASBR that is neither a PE nor a route reflector that receives its best RTC route for a prefix from an eBGP peer re-advertises that route (subject to export policies) to its eBGP and iBGP peers. When re-advertised routes are sent to eBGP peers, the ASBR modifies the NEXT_HOP and AS_PATH per standard BGP rules. The aggregation of RTC routes is not supported.
Using RT constraint routes
In general (ignoring iBGP-to-iBGP rules, add-path, best-external, and so on), the best VPN route for every prefix/NLRI in the RIB is sent to every peer supporting the VPN address family, but export policies may be used to prevent the advertisement of some prefix/NLRIs to specific peers. These export policies may be configured statically or created dynamically based on use of ORF or RTC with a peer. ORF and RTC are mutually exclusive on a session.
When RTC is configured on a session that also supports VPN address families using route targets (vpn-ipv4, vpn-ipv6, and so on), the advertisement of the VPN routes is affected as follows:
When the session comes up, the advertisement of the VPN routes is delayed briefly to allow RTC routes to be received from the peer.
After the initial delay, the received RTC routes are analyzed and acted upon. If S1 is the set of routes previously advertised to the peer and S2 is the set of routes that should be advertised based on the most recent received RTC routes, the following applies:
The set of routes in S1 but not in S2 should be withdrawn immediately (subject to the minimum route advertisement interval (MRAI)).
The set of routes in S2 but not in S1 should be advertised immediately (subject to MRAI).
If a default RTC route is received from a peer P1, the VPN routes that are advertised to P1 are the set that:
are eligible for advertisement to P1 per BGP route advertisement rules
have not been rejected by manually configured export policies
have not been advertised to the peer
Note: This applies regardless of whether P1 advertised the best route for the default RTC prefix.
In this context, a default RTC route is any of the following:
a route with NLRI length = zero
a route with NLRI value = origin AS and NLRI length = 32
a route with NLRI value = {origin AS+0x0002 | origin AS+0x0102 | origin AS+0x0202} and NLRI length = 48
If an RTC route for prefix A (origin-AS = A1, RT = A2/n, n > 48) is received from an iBGP peer I1 in autonomous system A1, the VPN routes that are advertised to I1 is the set that:
are eligible for advertisement to I1 per BGP route advertisement rules
have not been rejected by manually configured export policies
carry at least one route target extended community with value A2 in the n most significant bits
have not been advertised to the peer
Note: This applies regardless of whether I1 advertised the best route for A.If the best RTC route for a prefix A (origin-AS = A1, RT = A2/n, n > 48) is received from an IBGP peer I1 in autonomous system B, the VPN routes that are advertised to I1 is the set that:
are eligible for advertisement to I1 per BGP route advertisement rules
have not been rejected by manually configured export policies
carry at least one route target extended community with value A2 in the n most significant bits
have not been advertised to the peer
Note: This applies only if I1 advertised the best route for A.If the best RTC route for a prefix A (origin-AS = A1, RT = A2/n, n > 48) is received from an eBGP peer E1, the VPN routes that are advertised to E1 is the set that:
are eligible for advertisement to E1 per BGP route advertisement rules
have not been rejected by manually configured export policies
carry at least one route target extended community with value A2 in the n most significant bits
have not been advertised to the peer
Note: This applies only if E1 advertised the best route for A.
BGP fast reroute in a VPRN
BGP fast reroute is a feature that brings together indirection techniques in the forwarding plane and precomputation of BGP backup paths in the control plane to support fast reroute of BGP traffic around unreachable/failed next-hops. In a VPRN context BGP fast reroute is supported using VPN-IPv4 and VPN-IPv6 VPN routes. The supported VPRN scenarios are described in the following table.
| Ingress packet | Primary route | Backup route | Prefix independent convergence |
|---|---|---|---|
IPv4 (ingress PE) |
VPN-IPv4 route with next-hop A resolved by a LDP, RSVP or BGP tunnel |
VPN-IPv4 route with next-hop A resolved by a LDP, RSVP or BGP tunnel |
Yes |
IPv6 (ingress PE) |
VPN-IPv6 route with next-hop A resolved by a LDP, RSVP or BGP tunnel |
VPN-IPv6 route with next-hop B resolved by a LDP, RSVP or BGP tunnel |
Yes |
BGP fast reroute in a VPRN configuration
Configuring the enable-bgp-vpn-backup command under config>service>vprn causes only imported BGP-VPN routes to be considered when selecting the primary and backup paths.
This command is required to support fast failover of ingress traffic from one remote PE to another remote PE.
VPRN features
This section describes various VPRN features and any special capabilities or considerations as they relate to VPRN services.
IP interfaces
VPRN customer IP interfaces can be configured with most of the same options found on the core IP interfaces.
The advanced configuration options supported are:
-
DHCPv4 relay
VRRP for IPv4 interface
Secondary IP addresses
ICMP options
NTP broadcast receipt configuration options found on core IP interfaces are not supported on VPRN IP interfaces.
SAPs
This section provides information about SAPs.
IPv6 support for VPRN IP interfaces (in network mode)
VPRN IPv6 access interfaces are allowed to be configured to provide IPv6 VPN connectivity to customers.
IPv4 and IPv6 route table lookup entries are shared. Before adding routes for IPv6 destinations, route entries in the routed lookup table needs to be allocated for IPv6 addresses. This can be done using the config>system>resource-profile>router>max-ipv6-routes command. This command allocates route entries for /64 IPv6 prefix route lookups. The system does not allocate any IPv6 route entries by default and user needs to allocate some resources before using IPv6. For the command to take effect the node must be rebooted after making the change. For more information, see the following example and the 7210 SAS-Mxp, R6, R12, S, Sx, T Basic System Configuration Guide.
A separate route table (or a block in the route table) is used for IPv6 /128-bit prefix route lookup. A limited amount of IPv6 /128 prefixes route lookup entries is supported. The software enables lookups in this table by default (that is, no user configuration is required to enable IPv6 /128-bit route lookup).
In addition, the number IP subnets can be configured by the user using the configure> system>resource-profile>router>max-ip-subnets command. Suitable default are assigned to this parameter. Users can increase the number of subnets if they plan to more IPv6 addresses per IPv6 interface.
Following features and restrictions are applicable for IPv6 VPRN IP interfaces:
PE-CE routing - static routing and EBGP is supported
A limited amount of IPv6 /128 prefixes route lookup entries is supported on 7210 SAS platforms.
VRRP for VPRN IPv6 interfaces is not supported.
Encapsulations
The following SAP encapsulations are supported on the 7210 SAS VPRN service:
Ethernet null
Ethernet dot1q
QinQ
LAG
QoS policies
When applied to a VPRN SAP, service ingress QoS policies only create the unicast queues defined in the policy (as multicast is not supported in VPRN service).
Multicast is not supported in VPRN service.
Both Layer 2 (dot1p only) or Layer 3 criteria can be used in the QoS policies for traffic classification in an VPRN.
Filter policies
Ingress and egress IPv4 and IPv6 filter policies can be applied to VPRN SAPs.
CPU QoS for VPRN interfaces
Traffic bound to CPU received on VPRN access interfaces are policed/rate-limited and queued into CPU queues. The software allocates a policer per IP application or a set of IP applications, for rate-limiting CPU bound IP traffic from all VPRN access SAPs. The policers CIR/PIR values are set to appropriate values based on feature scaling and these values are not user configurable. The software allocates a set of queues for CPU bound IP traffic from all VPRN access SAPs. The queues are either shared by a set of IP applications or in some cases allocated to an IP application. The queues are shaped to appropriate rate based on feature scaling. The shaper rate is not user-configurable.
The instance of queues and policers used for traffic received on network port IP interfaces is different for traffic received from access port IP interfaces. Additionally, the network CPU queues receive higher priority than the access CPU queues, which provides better security and mitigates the risk of access traffic affecting the network side.
On the 7210 SAS-R6, the user can configure the IP DSCP value for self-generated traffic.
CE to PE routing protocols
The 7210 SAS VPRN supports the following PE to CE routing protocols:
eBGP (for both IPv4 and IPv6)
Static with both IPv4 and IPv6)
OSPF v2 (IPv4)
PE to PE tunneling mechanisms
The 7210 SAS supports multiple mechanisms to provide transport tunnels for the forwarding of traffic between PE routers within the 2547bis network.
The 7210 SAS VPRN implementation supports the use of:
RSVP-TE protocol to create tunnel LSP's between PE routers
LDP protocol to create tunnel LSP's between PE routers
These transport tunnel mechanisms provide the flexibility of using dynamically created LSPs where the service tunnels are automatically bound (the ‟autobind” feature) and the ability to provide specific VPN services with their own transport tunnels by explicitly binding SDPs if needed. When the autobind is used, all services traverse the same LSPs and do not allow alternate tunneling mechanisms or the ability to craft sets of LSP's with bandwidth reservations for specific customers as is available with explicit SDPs for the service.
Per VRF route limiting
The 7210 SAS allows setting the maximum number of routes that can be accepted in the VRF for a VPRN service. There are options to specify a percentage threshold at which to generate an event that the VRF table is near full and an option to disable additional route learning when full or only generate an event.
Exporting MP-BGP VPN routes
To reduce the number of MP-BGP VPN tunnels in a group of IP/MPLS PE routers that are part of the same L3 VPN instance, a hierarchy can be established by reexporting the VPN IP routes on a PE aggregation router (which can be an ABR node). In the case of VPRN service labels, reexporting VPN IP routes reduces the required MPLS FIB resources to the scale available on smaller access routers.
Use the config>service>vprn>allow-export-bgp-vpn command to configure the feature. This command enables the vrf-export and vrf-target export functions to include BGP-VPN routes that are installed in the VPRN route table.
When a route is installed in the VPRN route table, the route is exported as a new VPN-IP route to an MP-IBGP peer only; that is, the route is accepted by the VRF export policy but may be rejected by a BGP export policy. Assuming that the export policies have simple accept and reject actions, the new VPN-IP route is the same as the original VPN-IP route, except in the following cases.
The RD is changed to the value of the advertising VPRN.
The BGP next-hop is changed to a local address of the PE.
The label value is changed to the per-VRF label value of the advertising VPRN.
Configuration guidelines
The following configuration guidelines apply to this feature:
You must shut down and restart the VPRN context for any changes to the allow-export-bgp-vpn command to take effect.
You must configure the VPRN service with a loopback IP interface for the command to take effect.
SAPs cannot be configured in a VPRN service in which the allow-export-bgp-vpn command is enabled.
Spoke SDPs
Spoke-SDP termination into a Layer 3 service is not supported on 7210 SAS platforms.
Distributed services use service distribution points (SDPs) to direct traffic to another SR-Series router via service tunnels. SDPs are created on each participating SR-Series and then bound to a specific service. SDP can be created as either GRE or MPLS. See SDPs for information about configuring SDPs.
This feature provides the ability to cross-connect traffic entering on a spoke-SDP, used for Layer 2 services (VLLs or VPLS), on to an IES or VPRN service. From a logical point of view, the spoke-SDP entering on a network port is cross-connected to the Layer 3 service as if it entered by a service SAP. The main exception to this is traffic entering the Layer 3 service by a spoke-SDP is handled with network QoS policies not access QoS policies.
The following figure shows traffic terminating on a specific IES or VPRN service that is identified by the sdp-id and VC label present in the service packet.
The following figure shows a spoke-SDP terminating directly into an IES. In this case, a spoke-SDP could be tied to an Epipe or H-VPLS service. There is no configuration required on the PE connected to the CE.
All the routing protocols, including multicast, that are supported by VPRN are supported for spoke-sdp termination.
T-LDP status signaling for spoke SDPs terminating on IES/VPRN
T-LDP status signaling and PW active/standby signaling capabilities are supported on Ipipe and Epipe spoke SDPs.
Spoke-SDP termination on an IES or VPRN provides the ability to cross-connect traffic entering on a spoke-SDP, used for Layer 2 services (VLLs or VPLS), on to an IES or VPRN service. From a logical point of view the spoke-SDP entering on a network port is cross-connected to the Layer 3 service as if it had entered using a service SAP. The main exception to this is traffic entering the Layer 3 service using a spoke-SDP is handled with network QoS policies instead of access QoS policies.
When a SAP Down or SDP binding down status message is received by the PE in which the Ipipe or Ethernet spoke-SDP is terminated on an IES or VPRN interface, the interface is brought down and all associated routes are withdrawn in a similar way when the spoke-SDP goes down locally. The same actions are taken when the standby T-LDP status message is received by the IES/VPRN PE.
This feature can be used to provide redundant connectivity to a VPRN or IES from a PE providing a VLL service, as shown in the following figure.
GR Helper for CE-PE Routing Protocols
The GR helper function for BGP and OSPF between CE and PE is supported for routing protocols that are running in the default routing context.
Spoke-SDP Redundancy into IES/VPRN
This feature can be used to provide redundant connectivity to a VPRN or IES from a PE providing a VLL service, as shown in Active/standby VRF using resilient L2 circuits, using either Epipe or Ipipe spoke-SDPs.
In Active/standby VRF using resilient L2 circuits, PE1 terminates two spoke-SDPs that are bound to one SAP connected to CE1. PE1 chooses to forward traffic on one of the spoke SDPs (the active spoke-SDP), while blocking traffic on the other spoke-SDP (the standby spoke-SDP) in the transmit direction. PE2 and PE3 take any spoke-SDPs for which PW forwarding standby has been signaled by PE1 to an operationally down state.
7210 routers are expected to fulfill both functions (VLL and VPRN/IES PE). The following figure shows the model for spoke-SDP redundancy into a VPRN or IES.
Using OSPF in IP-VPNs
Using OSPF as a CE to PE routing protocol allows OSPF that is currently running as the IGP routing protocol to migrate to an IP-VPN backbone without changing the IGP routing protocol, introducing BGP as the CE-PE or relying on static routes for the distribution of routes into the service providers IP-VPN. The following features are supported:
Advertisement/redistribution of BGP-VPN routes as summary (type 3) LSAs flooded to CE neighbors of the VPRN OSPF instance. This occurs if the OSPF route type (in the OSPF route type BGP extended community attribute carried with the VPN route) is not external (or NSSA) and the locally configured domain-id matches the domain-id carried in the OSPF domain ID BGP extended community attribute carried with the VPN route.
OSPF sham links. A sham link is a logical PE-to-PE unnumbered point-to-point interface that essentially rides over the PE-to-PE transport tunnel. A sham link can be associated with any area and can therefore appear as an intra-area link to CE routers attached to different PEs in the VPN.
Service label mode of a VPRN
The 7210 SAS allocates one unique (platform-wide) service label per VRF. All VPN-IP routes exported by the PE from a particular VPRN service with that configuration have the same service label. When the PE receives a terminating MPLS packet, the service label value determines the VRF to which the packet belongs. A lookup of the IP packet DA in the forwarding table of the selected VRF determines the next-hop interface.
Multicast in IP-VPN applications
Applications for this feature include enterprise customer implementing a VPRN solution for their WAN networking needs, customer applications including stock-ticker information, financial institutions for stock and other types of trading data and video delivery systems.
The following figure depicts an example of multicast in an IP-VPN application. The provider domain encompasses the core routers (1 through 4) and the edge routers (5 through 10). The various IP-VPN customers each have their own multicast domain, VPN-1 (CE routers 12, 13 and 16) and VPN-2 (CE Routers 11, 14, 15, 17 and 18). In this VPRN example, the VPN-1 data generated by the customer behind router 16 is multicast only by PE router 9 to PE routers 6 and 7 for delivery to CE routers 12 and 13 respectively. Data for VPN-2 generated by the customer behind router 15 is forwarded by PE router 8 to PE routers 5, 7 and 10 for delivery to CE routers 18, 11, 14 and 17 respectively.
The demarcation of these domains is in the PE router (routers 5 through 10). The PE router participates in both the customer multicast domain and the provider multicast domain. The customer CE routers are limited to a multicast adjacency with the multicast instance on the PE created to support that specific customer IP-VPN. This way, customers are isolated from the provider core multicast domain and other customer multicast domains while the provider core routers only participate in the provider multicast domain and are isolated from all customer multicast domains.
The PE for a specific customer multicast domain becomes adjacent to the CE routers attached to that PE and to all other PE that participate in the IP-VPN (or customer) multicast domain. This is achieved by the PE, which encapsulates the customer multicast control data and multicast streams inside the provider multicast packets. These encapsulated packets are forwarded only to the PE nodes that are participating in the same MVPN domain and are part of the same customer VPRN. This prunes the distribution of the multicast control and data traffic to the PEs that do not participate in the customer multicast domain.
Multicast protocols supported in the provider network
An MVPN is defined by two sets of sites: the sender sites set and receiver sites set, with the following properties:
Hosts within the sender sites set could originate multicast traffic for receivers in the receiver sites set.
Receivers not in the receiver sites set should not be able to receive this traffic.
Hosts within the receiver sites set could receive multicast traffic originated by any host in the sender sites set.
Hosts within the receiver sites set should not be able to receive multicast traffic originated by any host that is not in the sender sites set.
A site could be both in the sender sites set and receiver sites set, which implies that hosts within such a site could both originate and receive multicast traffic. An extreme case is when the sender sites set is the same as the receiver sites set, in which case all sites could originate and receive multicast traffic from each other.
Sites within a specific MVPN can only be within the same organizations, which implies that an MVPN can be an intranet. A site may be in more than one MVPN, which implies that MVPNs may overlap. Not all sites of a specific MVPN have to be connected to the same service provider, which implies that an MVPN can span multiple service providers.
Another way to look at MVPN is to say that an MVPN is defined by a set of administrative policies. These policies determine the sender sites set and receiver site set. These policies are established by MVPN customers, but implemented by MVPN service providers using the existing BGP/MPLS VPN mechanisms, such as route targets, with extensions, as necessary.
MVPN using BGP control plane
The 7210 SAS supports next generation MVPN with MLDP and RSVP P2MP provider tunnels.
The Nokia implementation supports the following features:
MVPN is supported all 7210 SAS platforms as described in this document.
MVPN membership auto-discovery using BGP is supported.
PE-PE transmission of C-multicast routing using BGP is supported.
IPv4 is supported.
Inter-AS MVPN with option A is supported. This does not require any additional control or data plane implementations.
MVPN membership auto-discovery using BGP
BGP-based auto-discovery (AD) is performed by using a multicast VPN address family. Any PE router that attaches to an MVPN must issue a BGP update message containing an NLRI in this address family, along with a specific set of attributes.
The PE router uses route targets to specify MVPN route import and export. The route target may be the same as the one used for the corresponding unicast VPN, or it may be different. The PE router can specify separate import route targets for sender sites and receiver sites for a specific MVPN.
The route distinguisher (RD) that is used for the corresponding unicast VPN can also be used for the MVPN.
When BGP AD is enabled, PIM peering on the I-PMSI is disabled, so no PIM hellos are sent on the I-PMSI. C-tree to P-tunnel bindings are also discovered using BGP S-PMSI AD routes, instead of PIM join TLVs.
For example, if AD is disabled, the c-mcast-signaling bgp command fails and the following error message displays:
C-multicast signaling in BGP requires auto-discovery to be enabled
AD is enabled by default on the 7210 SAS-R6 and 7210 SAS-R12.
If c-mcast-signaling is set to bgp, the no auto-discovery command fails and the following error message displays:
C-multicast signaling in BGP requires auto-discovery to be enabled
When c-mcast-signaling is set to bgp, S-PMSI AD is always enabled (configuration is ignored).
Provider tunnel support
The following provider tunnels are supported:
mLDP inclusive provider tunnel
mLDP selective provider tunnel
RSVP P2MP LSPs inclusive provider tunnel
RSVP P2MP LSPs selective provider tunnel
Inter-AS VPRNs
Inter-AS IP-VPN services have been driven by the popularity of IP services and service provider expansion beyond the borders of a single Autonomous System (AS) or the requirement for IP VPN services to cross the AS boundaries of multiple providers. Three options for supporting inter-AS IP-VPNs are described in RFC 4364, BGP/MPLS IP Virtual Private Networks (VPNs).
The first option, referred to as Option-A (shown in the following figure), is considered inherent in any implementation. This method uses a back-to-back connection between separate VPRN instances in each AS. As a result, each VPRN instance views the inter-AS connection as an external interface to a remote VPRN customer site. The back-to-back VRF connections between the ASBR nodes require individual sub-interfaces, one per VRF.
The second option, referred to as Option-B (Inter-AS Option-B), relies heavily on the AS Boundary Routers (ASBRs) as the interface between the autonomous systems. This approach enhances the scalability of the eBGP VRF-to-VRF solution by eliminating the need for per-VPRN configuration on the ASBRs. However it requires that the ASBRs provide a control plan and forwarding plane connection between the autonomous systems. The ASBRs are connected to the PE nodes in its local autonomous system using iBGP either directly or through route reflectors.
This means the ASBRs receive all the VPRN information and forwards these VPRN updates, VPN-IPV4, to all its EBGP peers, ASBRs, using itself as the next-hop. It also changes the label associated with the route. This means the ASBRs must maintain an associate mapping of labels received and labels issued for those routes. The peer ASBRs, in turn, forward those updates to all local IBGP peers.
This form of inter-AS VPRNs does not require instances of the VPRN to be created on the ASBR, as in option-A, as a result there is less management overhead. This is also the most common form of Inter-AS VPRNs used between different service providers as all routes advertised between autonomous systems can be controlled by route policies on the ASBRs.
The third option, referred to as Option-C (shown in the following figure), allows for a higher scale of VPRNs across AS boundaries but also expands the trust model between ASNs. As a result this model is typically used within a single company that may have multiple ASNs for various reasons.
This model differs from Option-B, in that in Option-B all direct knowledge of the remote AS is contained and limited to the ASBR. As a result, in option-B the ASBR performs all necessary mapping functions and the PE routers do not need perform any additional functions then in a non-Inter-AS VPRN.
With Option-C, knowledge from the remote AS is distributed throughout the local AS. This distribution allows for higher scalability but also requires all PEs and ASBRs involved in the Inter-AS VPRNs to participate in the exchange of inter-AS routing information.
In Option-C, the ASBRs distribute reachability information for remote PE system IP addresses only. This is done between the ASBRs by exchanging MP-eBGP labeled routes, using RFC 3107, Carrying Label Information in BGP-4.
Distribution of VPRN routing information is handled by either direct MP-BGP peering between PEs in the different ASNs or more likely by one or more route reflectors in ASN.

ALA48>config>router# Configuring VPRN protocols - BGP
The autonomous system number and router ID configured in the VPRN context only applies to that particular service.
The minimal parameters that should be configured for a VPRN BGP instance are:
Specify an autonomous system number for the router. See Configuring global VPRN parameters.
Specify a router ID - Note that if a new or different router ID value is entered in the BGP context, then the new values takes precedence and overwrites the VPRN-level router ID. See Configuring global VPRN parameters.
Specify a VPRN BGP peer group.
Specify a VPRN BGP neighbor with which to peer.
Specify a VPRN BGP peer-AS that is associated with the above peer.
VPRN BGP is administratively enabled upon creation. Minimally, to enable VPRN BGP in a VPRN instance, you must associate an autonomous system number and router ID for the VPRN service, create a peer group, neighbor, and associate a peer ASN. There are no default VPRN BGP groups or neighbors. Each VPRN BGP group and neighbor must be explicitly configured.
All parameters configured for VPRN BGP are applied to the group and are inherited by each peer, but a group parameter can be overridden on a specific basis. VPRN BGP command hierarchy consists of three levels:
the global level
the group level
the neighbor level
Use the following commands to configure VPRN BGP groups and neighbors.
config>service>vprn>bgp# (global level)
group (group level)
neighbor (neighbor level)For more information about the BGP protocol, see the 7210 SAS-Mxp, R6, R12, S, Sx, T Router Configuration Guide.
Configuring VPRN BGP group and neighbor parameters
A group is a collection of related VPRN BGP peers. The group name should be a descriptive name for the group. Follow your group, name, and ID naming conventions for consistency and to help when troubleshooting faults.
All parameters configured for a peer group are applied to the group and are inherited by each peer (neighbor), but a group parameter can be overridden on a specific neighbor-level basis.
After a group name is created and options are configured, neighbors can be added within the same autonomous system to create IBGP connections or neighbors in different autonomous systems to create EBGP peers. All parameters configured for the peer group level are applied to each neighbor, but a group parameter can be overridden on a specific neighbor basis.

*A:ALA-1>config>service#Configuring a VPRN interface
Interface names associate an IP address to the interface, and then associate the IP interface with a physical port. The logical interface can associate attributes like an IP address, port, Link Aggregation Group (LAG) or the system.
There are no default interfaces.
Note that you can configure a VPRN interface as a loopback interface by issuing the loopback command instead of the sap sap-id command. The loopback flag cannot be set on an interface where a SAP is already defined and a SAP cannot be defined on a loopback interface.
When using mtrace/mstat in a Layer 3 VPN context then the configuration for the VPRN should have a loopback address configured which has the same address as the core instance's system address (BGP next-hop).
See OSPF configuration commands (IPv4 only) for CLI commands and syntax.

A SAP is a combination of a port and encapsulation parameters which identifies the service access point on the interface and within the 7210 SAS. Each SAP must be unique within a router. A SAP cannot be defined if the interface loopback command is enabled.
When configuring VPRN interface SAP parameters, a default QoS policy is applied to each ingress and egress SAP. Additional QoS policies and scheduler policies must be configured in the config>qos context. Filter policies are configured in the config>filter context and must be explicitly applied to a SAP. There are no default filter policies.

Description
This command administratively disables an entity. When disabled, an entity does not change, reset, or remove any configuration settings or statistics.
The operational state of the entity is disabled as well as the operational state of any entities contained within. Many objects must be shut down before they may be deleted.
Services are created in the administratively down (shutdown) state. When a no shutdown command is entered, the service becomes administratively up and then tries to enter the operationally up state. Default administrative states for services and service entities is described as follows in Special Cases.
The no form of this command places the entity into an administratively enabled state.
If the ASN was previously changed, the BGP ASN inherits the new value.
Special Cases
- Service Admin State
Bindings to an SDP within the service are put into the out-of-service state when the service is shut down. While the service is shut down, all customer packets are dropped and counted as discards for billing and debugging purposes.
A service is regarded as operational providing that one IP Interface SAP and one SDP is operational.
- VPRN BGP
This command disables the BGP instance on the specified IP interface. Routes learned from a neighbor that is shut down are immediately removed from the BGP database and RTM. If BGP is globally shut down, all group and neighbor interfaces are shut down operationally. If a BGP group is shut down, all member neighbor interfaces are shut down operationally. If a BGP neighbor is shut down, just that neighbor interface is operationally shut down.

Syntax

Context
config>service
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command creates or edits a Virtual Private Routed Network (VPRN) service instance.
If the service-id does not exist, a context for the service is created. If the service-id exists, the context for editing the service is entered.
VPRN services allow the creation of customer-facing IP interfaces in the same routing instance used for service network core routing connectivity. VPRN services require that the IP addressing scheme used by the subscriber must be unique between it and other addressing schemes used by the provider and potentially the entire Internet.
IP interfaces defined within the context of an VPRN service ID must have a SAP created as the access point to the subscriber network.
When a service is created, the customer keyword and customer-id must be specified and associate the service with a customer. The customer-id must already exist, having been created using the customer command in the service context. When a service is created with a customer association, it is not possible to edit the customer association. The service must be deleted and recreated with a new customer association.
When a service is created, the use of the customer customer-id is optional to navigate into the service configuration context. If attempting to edit a service with the incorrect customer-id results in an error.
Multiple VPRN services are created to separate customer-owned IP interfaces. More than one VPRN service can be created for a single customer ID. More than one IP interface can be created within a single VPRN service ID. All IP interfaces created within an VPRN service ID belongs to the same customer.
The no form of this command deletes the VPRN service instance with the specified service-id. The service cannot be deleted until all the IP interfaces and all routing protocol configurations defined within the service ID have been shutdown and deleted.
Parameters
- service-id
Specifies the service ID number identifying the service in the service domain. This ID must be unique to this service and may not be used for any other service of any type. The service-id must be the same number used for every 7210 SAS on which this service is defined.
- customer customer-id
Specifies an existing customer ID number to be associated with the service. This parameter is required on service creation and optional for service editing or deleting.
- create
Mandatory keyword for creating a VPRN service.
allow-export-bgp-vpn
Syntax
[no] allow-export-bgp-vpn
Context
config>service>vprn
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command causes the vrf-export and vrf-target commands to include BGP-VPN routes installed in the VPRN route table. These routes are usually not readvertisable as VPN-IP routes because of split-horizon.
When a BGP-VPN route is reexported, the route distinguisher and label values are rewritten according to the configuration of the reexporting VPRN.
This command requires the vrpn context to be shut down and restarted for changes to take effect.
This command can only be configured with VPRN loopback interfaces.
The no form of this command reverts to the default value.
Default
no allow-export-bgp-vpn
auto-bind-tunnel
Syntax
auto-bind-tunnel
Context
config>service>vprn
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
Commands in this context configure automatic binding of a VPRN service using tunnels to MP-BGP peers.
Users must configure the resolution option to enable auto-bind resolution to tunnels in TTM. If the resolution option is explicitly set to disabled, the auto-binding to tunnel is removed.
If the resolution is set to any, any supported tunnel type within the VPRN context is selected following the TTM preference. If one or more explicit tunnel types are specified using the resolution-filter option, only these tunnel types are selected again following the TTM preference.
The following tunnel types are supported in a VPRN context in order of preference: RSVP and LDP. The BGP tunnel type is not explicitly configured and is therefore implicit. It is always preferred over any other tunnel type enabled in the auto-bind-tunnel context.
The ldp value instructs BGP to search for an LDP LSP with a FEC prefix corresponding to the address of the BGP next hop.
The rsvp value instructs BGP to search for the best metric RSVP LSP to the address of the BGP next hop. This address can correspond to the system interface or to another loopback used by the BGP instance on the remote node. The LSP metric is provided by MPLS in the tunnel table. In the case of multiple RSVP LSPs with the same lowest metric, BGP selects the LSP with the lowest tunnel ID.
Users must set the resolution to filter to activate the list of tunnel-types configured under the resolution-filter.
When an explicit SDP to a BGP next-hop is configured in a VPRN service ( using the configure>service>vprn>spoke-sdp command), it overrides the auto-bind-tunnel selection for that BGP next hop only. There is no support for reverting automatically to the auto-bind-tunnel selection if the explicit SDP goes down. The user must delete the explicit spoke-SDP in the VPRN service context to resume using theauto-bind-tunnel selection for the BGP next hop.

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command specifies the source IP address for the group range. Whenever a (*,G) report is received in the range specified by grp-range start and end parameters, it is translated to an (S,G) report with the value of this object as the source address.
Parameters
- ip-address
Specifies the IP address for sending data.
maximum-ipv6-routes
Syntax
maximum-ipv6-routes number [log-only] [threshold percent]
no maximum-ipv6-routes
Context
config>service>vprn
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command specifies the maximum number of remote IPv6 routes that can be held within a VPN routing/forwarding (VRF) context. Local, host, static, and aggregate routes are not counted.
The VPRN service ID must be in a shutdown state before maximum-ipv6-routes command parameters can be modified.
If the log-only parameter is not specified and the maximum-routes value is set below the existing number of routes in a VRF, the offending RIP peer (if applicable) is brought down (but the VPRN instance remains up). BGP peering remains up, but the exceeding BGP routes are not added to the VRF.
The maximum route threshold can dynamically change to increase the number of supported routes even when the maximum has already been reached. Protocols resubmit the routes that were initially rejected.
The no form of this command disables any limit on the number of routes within a VRF context. Issue the no form of this command only when the VPRN instance is shut down.
Default
0 or disabled
Parameters
- number
Specifies the maximum number of routes to be held in a VRF context.
- log-only
Keyword to specify that if the maximum limit is reached, only log the event. This keyword does not disable the learning of new routes.
- threshold percent
Specifies the percentage at which a warning log message and SNMP trap should be set. There are two warnings, the first is a mid-level warning at the threshold value set, and the second is a high-level warning at a level between the maximum number of routes and the mid-level rate ([mid+max] / 2).

Description
This command configures DSCP or dot1p re-marking for self-generated application traffic. When an application is configured using this command, the specified DSCP name/value is used for all packets generated by this application within the router instance in which it is configured. The instances can be base router, VPRN service, or management.
The values configured in this command do the following:
set the DSCP bits in the IP packet
map to the FC
based on this FC, the egress QoS policy sets the Ethernet 802.1p and MPLS EXP bits. This includes ARP and IS-IS packets that, because of their nature, do not carry DSCP bits.
DSCP value in the egress IP header is as configured in this command
Only one DSCP name/value can be configured per application. If multiple entries are configured, the subsequent entry overrides the previously configured entry.
The no form of this command reverts to the default value.
Parameters
- dscp-app-name
Specifies the DSCP application name.
- dscp-value
Specifies a value when this packet egresses. The respective egress policy should provide the mapping for the DSCP value to either LSP-EXP bits or IEEE 802.1p (dot1p) bits, otherwise the default mapping applies.
- dscp-name
Specifies the DSCP name.
- dot1p-priority
Specifies the dot1p priority.

Context
config>service>vprn
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command creates static route entries within the associated router instance. When configuring a static route, the next-hop, indirect, or black-hole parameters must be configured.
The no form of this command deletes the static route entry. If a static route needs to be removed when multiple static routes exist to the same destination, as many parameters as are required to uniquely identify the static route must be entered.
If a CPE connectivity check target address is already being used as the target address in a different static route, the cpe-check parameters must match. If they do not, the new configuration command are rejected.
If a static-route command is issued with no cpe-check target but the destination prefix/netmask and next-hop matches a static route that did have an associated cpe-check, the cpe-check test is removed from the associated static route.
Parameters
- ip-prefix
Specifies the destination address of the aggregate route in dotted-decimal notation.
- netmask
Specifies the subnet mask in dotted-decimal notation.
- ip-int-name
Specifies the name of the IP interface. Interface names must be unique within the group of defined IP interfaces for config router interface and config service ies interface commands. An interface name cannot be in the form of an IP address. If the string contains special characters (#, $, spaces, and so on), the entire string must be enclosed within double quotes.
- ip-address
Specifies the IP address of the IP interface. The ip-addr portion of the address command specifies the IP host address that is used by the IP interface within the subnet. This address must be unique within the subnet and specified in dotted-decimal notation.
- enable
Keyword to re-enable a disabled static route. Static routes can be administratively enabled or disabled. To enable a static route, it must be uniquely identified by the IP address, mask, and any other parameter that is required to identify the exact static route.
The administrative state is maintained in the configuration file.
- disable
Keyword to disable a static route while maintaining the static route in the configuration. Static routes can be administratively enabled or disabled. To enable a static route, it must be uniquely identified by the IP address, mask, and any other parameter that is required to identify the exact static route.
The administrative state is maintained in the configuration file.
- interval seconds
Optionally specifies the interval between ICMP pings to the target IP address.
- drop-count count
Optionally specifies the number of consecutive ping-replies that must be missed to declare the CPE down and to de-active the associated static route.
- log
Optional keyword to enable the ability to log transitions between active and in-active based on the CPE connectivity check. Events should be sent to the system log, syslog, and SNMP traps.
- next-hop [ip-address | ip-int-name]
Specifies the directly connected next-hop IP address used to reach the destination. If the next hop is over an unnumbered interface, the ip-int-name of the unnumbered interface (on this node) can be configured.
The next-hop keyword and the indirect or black-hole keywords are mutually exclusive. If an identical command is entered (with the exception of either the indirect or black-hole parameters), this static route is replaced with the newly entered command, and unless specified, the respective defaults for preference and metric are applied.
The ip-addr configured here can be either on the network side or the access side on this node. This address must be associated with a network directly connected to a network configured on this node.
- ipsec-tunnel ipsec-tunnel-name
Specifies an IPSec tunnel name, up to 32 characters.
- indirect ip-address
Specifies that the route is indirect and specifies the next-hop IP address used to reach the destination.
The configured ip-addr is not directly connected to a network configured on this node. The destination can be reachable via multiple paths. The static route remains valid as long as the address configured as the indirect address remains a valid entry in the routing table. Indirect static routes cannot use an ip-prefix/mask to another indirect static route.
The indirect keyword and the next-hop or black-hole keywords are mutually exclusive. If an identical command is entered (with the exception of either the next-hop or black-hole parameters), this static route is replaced with the newly entered command and unless specified the respective defaults for preference and metric are be applied.
The ip-addr can be either on the network or the access side and is at least one hop away from this node.
- black-hole
Keyword to specify a blackhole route, meaning that if the destination address on a packet matches this static route it is silently discarded.
The black-hole keyword is mutually exclusive with either the next-hop or indirect keywords. If an identical command is entered, with exception of either the next-hop or indirect parameters, the static route is replaced with the new command, and unless specified, the respective defaults for preference and metric are applied.
- preference preference
Specifies the preference of this static route (as opposed to the routes from different sources such as BGP or OSPF), expressed as a decimal integer. When modifying the preference value of an existing static route, the metric does not change unless specified.
If multiple routes are learned with an identical preference using the same protocol, the lowest cost route is used. If multiple routes are learned with an identical preference using the same protocol and the costs (metrics) are equal, the decision of which route to use is determined by the configuration of the ecmp command.
- metric metric
Specifies the cost metric for the static route, expressed as a decimal integer. This value is used when importing this static route into other protocols, such as OSPF. This value is also used to determine the static route to install in the forwarding table. When modifying the metric values of an existing static route, the preference does not change unless specified.
If there are multiple static routes with the same preference but unequal metrics, the lower cost (metric) route is installed. If there are multiple static routes with equal preference and metrics, ECMP rules apply. If there are multiple routes with unequal preferences, the lower preference route is installed.
- tag
Keyword to add a 32-bit integer tag to the static route. The tag is used in route policies to control distribution of the route into other protocols.
- bfd-enable
Keyword to associate the state of the static route to a BFD session between the local system and the configured next hop. This keyword cannot be configured if the next hop is indirect or a black-hole keyword is specified. See the 7210 SAS-Mxp, R6, R12, S, Sx, T Router Configuration Guide for more information about the protocols and platforms that support BFD.
- cpe-check target-ip-address
Specifies the IP address of the target CPE device. ICMP pings are sent to this target IP address. This parameter must be configured to enable the CPE connectivity feature for the associated static route. The target-ip-address cannot be in the same subnet as the static route subnet to avoid possible circular references. This option and BFD support on a specified static route are mutually exclusive.

SDP commands
spoke-sdp
Syntax
[no] spoke-sdp sdp-id
Context
config>service>vprn
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command binds a service to an existing SDP. The SDP defines the transport tunnel to which this VPRN service is bound.
The SDP has an operational state that determines the operational state of the SDP within the service; for example, if the SDP is administratively or operationally down, the SDP for the service is down.
The SDP must already exist in the config>service>sdp context before it can be associated with a VPRN service. If the sdp sdp-id is not already configured, an error message is generated. If the sdp-id exists, a binding between the specific sdp-id and service is created.
SDPs must be explicitly associated and bound to a service to allow far-end 7210 SAS devices to participate in the service.
The no form of this command removes the SDP binding from the service; the SDP configuration is not affected. When the SDP binding is removed, no packets are forwarded to the far-end router.
Special Cases
- VPRN
Several SDPs can be bound to a VPRN service. Each SDP must be destined for a different 7210 SAS router. If two sdp-id bindings terminate on the same 7210 SAS, an error occurs and the second SDP binding is rejected.
Parameters
- sdp-id
Specifies the SDP identifier. Allowed values are integers for existing SDPs.
- vc-id
Specifies the virtual circuit identifier.
spoke-sdp
Syntax
spoke-sdp sdp-id [:vc-id] vc-type {ether | ipipe} [create]
no spoke-sdp sdp-id [:vc-id] vc-type {ether | ipipe} [create]
Context
config>service>vprn>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command binds a service to an existing SDP.
A spoke-SDP is treated like the equivalent of a traditional bridge ‟port” where flooded traffic received on the spoke-SDP is replicated on all other ‟ports” (other spoke and mesh SDPs or SAPs) and not transmitted on the port it was received.
The SDP has an operational state that determines the operational state of the SDP within the service; for example, if the SDP is administratively or operationally down, the SDP for the service is down.
The SDP must already be defined in the config>service>sdp context to associate an SDP with a service. If the sdp sdp-id is not already configured, an error message is generated. If the sdp-id does exist, a binding between that sdp-id and the service is created.
SDPs must be explicitly associated and bound to a service. If an SDP is not bound to a service, no far-end devices can participate in the service.
Class-based forwarding is not supported on a spoke-SDP used for termination on an IES or VPRN services. All packets are forwarded over the default LSP.
The no form of this command removes the SDP binding from the service. The SDP configuration is not affected; only the binding of the SDP to a service. When removed, no packets are forwarded to the far-end router.
Special Cases
- VPRN
Several SDPs can be bound to a VPRN service. Each SDP must be destined for a different router. If two SDP ID bindings terminate on the same 7210 SAS, an error occurs and the second SDP is binding is rejected.
Parameters
- sdp-id
Specifies the SDP identifier.
- vc-id
Specifies the virtual circuit identifier.
- vc-type
Specifies the encapsulation and pseudowire type for the spoke-SDP.

Description
This command associates an IP filter policy with an ingress or egress SAP or IP interface. An IP filter policy can be associated with spoke SDPs. Filter policies control the forwarding and dropping of packets based on IP or MAC matching criteria.
The filter command is used to associate a filter policy that has a specified ip-filter-id with an ingress or egress SAP. The ip-filter-id must already be defined before the filter command is executed. If the filter policy does not exist, the operation fails and an error message is returned.
In general, filters applied to SAPs (ingress or egress) apply to all packets on the SAP. One exception is non-IP packets are not applied to IP match criteria, so the default action in the filter policy applies to these packets.
The no form of this command removes any configured filter ID association with the SAP or IP interface. The filter ID is not removed from the system unless the scope of the created filter is set to local. To avoid deletion of the filter ID and only break the association with the service object, use the scope command within the filter definition to change the scope to local or global. The default scope of a filter is local.
Parameters
- ip ip-filter-id
Specifies an IP filter policy. The filter ID must already exist within the created IP filters.
Interface commands
interface
Syntax
interface ip-int-name
no interface ip-int-name
Context
config>service>vprn
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command creates a logical IP routing interface for a VPRN. When created, attributes like an IP address and SAP can be associated with the IP interface.
This command creates and maintains IP routing interfaces within VPRN service IDs. The interface command can be executed in the context of a VPRN service ID. The IP interface created is associated with the service core network routing instance and default routing table. The typical use for IP interfaces created in this manner is for subscriber Internet access.
Interface names are case sensitive and must be unique within the group of IP interfaces defined by the config router interface and config service vprn interface commands. Interface names must not be in the dotted decimal notation of an IP address; for example, the name ‟1.1.1.1” is not allowed, but ‟int-1.1.1.1” is allowed. Show commands for router interfaces use either interface names or the IP addresses. Use unique IP address values and IP address names to maintain clarity. It could be unclear to the user if the same IP address and IP address name values are used. Although not recommended, duplicate interface names can exist in different router instances.
The available IP address space for local subnets and routes is controlled using the config router service-prefix command. The service-prefix command administers the allowed subnets that can be defined on service IP interfaces. It also controls the prefixes that may be learned or statically defined with the service IP interface as the egress interface. This allows segmenting the IP address space into config router and config service domains.
When a new name is entered, a new logical router interface is created. When an existing interface name is entered, the user enters the router interface context for editing and configuration.
By default, no IP interface names are defined within the system. All VPRN IP interfaces must be explicitly defined. Interfaces are created in an enabled state.
The no form of this command removes the interface and all the associated configuration. The interface must be administratively shut down before issuing the no interface command.
For VPRN services, the IP interface must be shut down before the SAP on that interface may be removed. VPRN services do not have the shutdown command in the SAP CLI context. VPRN service SAPs rely on the interface status to enable and disable them.
Parameters
- ip-int-name
Specifies the name of the IP interface. Interface names must be unique within the group of defined IP interfaces for config router interface and config service vprn interface commands. An interface name cannot be in the form of an IP address. Interface names can be from 1 to 32 alphanumeric characters. If the string contains special characters (#, $, spaces, and so on), the entire string must be enclosed within double quotes.
If ip-int-name already exists within the service ID, the context is changed to maintain that IP interface. If ip-int-namealready exists within another service ID or is an IP interface defined within the config router commands, an error occurs and the context is not changed to that IP interface. If ip-int-name does not exist, the interface is created and the context is changed to that interface for further command processing.
address
Syntax
address {ip-address/mask | ip-address netmask} [broadcast [all-ones | host-ones]
no address
Context
config>service>vprn>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command assigns an IP address, IP subnet, and broadcast address format to a VPRN IP router interface. Only one IP address can be associated with an IP interface.
An IP address must be assigned to each VPRN IP interface. An IP address and a mask are used together to create a local IP prefix. The defined IP prefix must be unique within the context of the routing instance. It cannot overlap with other existing IP prefixes defined as local subnets on other IP interfaces in the same routing context within the 7210 SAS.
The local subnet that the address command defines must be part of the services address space within the routing context using the config router service-prefix command. The default is to disallow the complete address space to services. When a portion of the address space is allocated as a service prefix, that portion can be made unavailable for IP interfaces defined within the config>router>interface context for network core connectivity with the exclude option in the config router service-prefix command.
The IP address for the interface can be entered in either CIDR (Classless Inter-Domain Routing) or traditional dotted-decimal notation. The show commands display CIDR notation and are stored in configuration files.
By default, no IP address or subnet association exists on an IP interface until it is explicitly created.
Use the no form of this command to remove the IP address assignment from the IP interface. When the no address command is entered, the interface becomes operationally down.
| Address | Administrative state | Operational state |
|---|---|---|
No address |
up |
down |
No address |
down |
down |
1.1.1.1 |
up |
up |
1.1.1.1 |
down |
down |
The operational state is a read-only variable, and the only controlling variables are the address and admin states. The address and admin states are independent and can be set independently. If an interface is in an adminstratively up state and an address is assigned, it becomes operationally up and the protocol interfaces and the MPLS LSPs associated with that IP interface are reinitialized.
Parameters
- ip-address
Specifies the IP address of the IP interface. The ip-address portion of the address command specifies the IP host address that is used by the IP interface within the subnet. This address must be unique within the subnet and specified in dotted-decimal notation.
- /
The forward slash is a parameter delimiter and separates the ip-address portion of the IP address from the mask that defines the scope of the local subnet. No spaces are allowed between the ip-address, the ‟/” and the mask-length parameter. If a forward slash is not immediately following the ip-address, a dotted-decimal mask must follow the prefix.
- mask
Specifies the subnet mask length when the IP prefix is specified in CIDR notation. When the IP prefix is specified in CIDR notation, a forward slash (/) separates the ip-address from the mask-lengthparameter. The mask length parameter indicates the number of bits used for the network portion of the IP address; the remainder of the IP address is used to determine the host portion of the IP address. A mask length of 32 is reserved for system IP addresses.
- netmask
Specifies the subnet mask in dotted-decimal notation. When the IP prefix is not specified in CIDR notation, a space separates the ip-address from a traditional dotted-decimal mask. The mask parameter indicates the complete mask that is used in a logical ‟AND” function to derive the local subnet of the IP address. A mask of 255.255.255.255 is reserved for system IP addresses.
- broadcast
Specifies to overrides the default broadcast address used by the IP interface when sourcing IP broadcasts on the IP interface. If no broadcast format is specified for the IP address, the default value is host-ones, which indicates a subnet broadcast address. Use this parameter to change the broadcast address to all-ones or revert to a broadcast address of host-ones.
The broadcast format on an IP interface can be specified when the IP address is assigned or changed.
This parameter does not affect the type of broadcasts that can be received by the IP interface. A host sending either the local broadcast (all-ones) or the valid subnet broadcast address (host-ones) is received by the IP interface.
- all-ones
Keyword following the broadcast parameter that specifies the broadcast address used by the IP interface for this IP address is 255.255.255.255, also known as the local broadcast.
- host-ones
Keyword following the broadcast parameter that specifies that the broadcast address used by the IP interface for this IP address is the subnet broadcast address. This is an IP address that corresponds to the local subnet described by the ip-address and the mask-length or mask with all the host bits set to binary one. This is the default broadcast address used by an IP interface.
The broadcast parameter within the address command does not have a negation feature, which is usually used to revert a parameter to the default value. To change the broadcast type to host-ones after being changed to all-ones, the address command must be executed with the broadcast parameter defined.
allow-directed-broadcasts
Syntax
[no] allow-directed-broadcasts
Context
config>service>vprn>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command controls the forwarding of directed broadcasts out of the IP interface.
A directed broadcast is a packet received on a local router interface destined for the subnet broadcast address on another IP interface. The allow-directed-broadcasts command on an IP interface enables or disables the transmission of packets destined for the subnet broadcast address of the egress IP interface.
When enabled, a frame destined for the local subnet on this IP interface is sent as a subnet broadcast out this interface. Care should be exercised when allowing directed broadcasts, because it is a well-known mechanism used for denial-of-service attacks.
When disabled, directed broadcast packets discarded at this egress IP interface are counted in the normal discard counters for the egress SAP.
By default, directed broadcasts are not allowed and are discarded at this egress IP interface.
The no form of this command disables the forwarding of directed broadcasts out of the IP interface.
Default
no allow-directed-broadcasts
bfd
Syntax

config>service>ies>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command specifies the BFD parameters for the associated IP interface. If no parameters are defined, the default value are used.
The multiplier specifies the number of consecutive BFD messages that must be missed from the peer before the BFD session state is changed to down and the upper level protocols (OSPF, IS-IS, BGP) are notified of the fault.
See the 7210 SAS-Mxp, R6, R12, S, Sx, T Router Configuration Guide for information about the routing and MPLS protocols and features that can use BFD for protection on 7210 SAS platforms.
The no form of this command removes BFD from the associated IGP protocol adjacency.
Default
no bfd
Parameters
- transmit-interval
Sets the transmit interval for the BFD session.
- receive receive-interval
Sets the receive interval for the BFD session.
- multiplier multiplier
Sets the multiplier for the BFD session.
- echo-receive echo-interval

local-proxy-arp
Syntax
[no] local-proxy-arp
Context
config>service>vprn>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command enables local proxy ARP. When local proxy ARP is enabled on an IP interface, the system responds to all ARP requests for IP addresses belonging to the subnet with its own MAC address, and therefore becomes the forwarding point for all traffic between hosts in that subnet. When the local-proxy-arp command is enabled, ICMP redirects on the ports associated with the service are automatically blocked.
Default
no local-proxy-arp
loopback
Syntax
[no] loopback
Context
config>service>vprn>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command specifies that the associated interface is a loopback interface that has no associated physical interface. As a result, the associated interface cannot be bound to a SAP.
When using mtrace/mstat in a Layer 3 VPN context, the configuration for the VPRN should have a loopback address configured that has the same address as the core instance system address (BGP next hop).
proxy-arp-policy
Syntax
[no] proxy-arp-policy policy-name [policy-name...(up to 5 max)]
Context
config>service>vprn>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command enables a proxy ARP policy for the interface.
The no form of this command disables the proxy ARP capability.
Default
no proxy-arp
Parameters
- policy-name
Specifies the export route policy name. Allowed values are any string up to 32 characters composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, and so on), the entire string must be enclosed within double quotes.
remote-proxy-arp
Syntax
[no] remote-proxy-arp
Context
config>service>vprn>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command enables remote proxy ARP on the interface.
Remote proxy ARP is similar to proxy ARP. It allows the router to answer an ARP request on an interface for a subnet that is not provisioned on that interface. This allows the router to forward to the other subnet on behalf of the requester. To distinguish remote proxy ARP from local proxy ARP, local proxy ARP performs a similar function but only when the requested IP is on the receiving interface.
Default
no remote-proxy-arp
secondary
Syntax
secondary {ip-address/mask | ip-address netmask} [broadcast {all-ones | host-ones}] [igp-inhibit]
no secondary {ip-address/mask | ip-address netmask}
Context
config>service>vprn>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command assigns up to 64 secondary IP addresses to the interface, including the primary IP address. Each address can be configured in an IP address, IP subnet, or broadcast address format.
Parameters
- ip-address
Specifies the IP address of the IP interface. The ip-address portion of the address command specifies the IP host address that is used by the IP interface within the subnet. This address must be unique within the subnet and specified in dotted-decimal notation.
- /
The forward slash is a parameter delimiter that separates the ip-address portion of the IP address from the mask that defines the scope of the local subnet. No spaces are allowed between the ip-address, the "/" and the mask parameter. If a forward slash does not immediately follow the ip-address, a dotted decimal netmask must follow the prefix.
- mask
Specifies the subnet mask length when the IP prefix is specified in CIDR notation. When the IP prefix is specified in CIDR notation, a forward slash (/) separates the ip-address from the mask parameter. The mask parameter indicates the number of bits used for the network portion of the IP address; the remainder of the IP address is used to determine the host portion of the IP address. A mask length of 32 is reserved for system IP addresses.
- netmask
Specifies the subnet mask in dotted-decimal notation. When the IP prefix is not specified in CIDR notation, a space separates the ip-address from a traditional dotted-decimal mask. The netmask parameter indicates the complete mask that is used in a logical ‟AND” function to derive the local subnet of the IP address. A netmask of 255.255.255.255 is reserved for system IP addresses.
- broadcast {all-ones | host-ones}
Optional keyword to override the default broadcast address used by the IP interface when sourcing IP broadcasts on the IP interface. If no broadcast format is specified for the IP address, the default value is host-ones, which indicates a subnet broadcast address. Use this parameter to change the broadcast address to all-ones or revert to a broadcast address of host-ones.
The broadcast parameter within the address command does not have a negation feature, which is usually used to revert a parameter to the default value. To change the broadcast type to host-ones after being configured as all-ones, the address command must be executed with the broadcast parameter defined. The broadcast format on an IP interface can be specified when the IP address is assigned or changed.
This parameter does not affect the type of broadcasts that can be received by the IP interface. A host sending either the local broadcast (all-ones) or the valid subnet broadcast address (host-ones) is received by the IP interface
- igp-inhibit
Keyword to specify that the secondary IP address should not be recognized as a local interface by the running IGP.
static-arp

Context
config>service>vprn>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures a static ARP entry associating a subscriber IP address with a MAC address for the core router instance. This static ARP appears in the core routing ARP table. A static ARP can be configured only if it exists on the network attached to the IP interface. If an entry for a particular IP address already exists and a new MAC address is configured for the IP address, the existing MAC address is replaced with the new MAC address.
The no form of this command removes a static ARP entry.
Parameters
- ip-address
Specifies the IP address for the static ARP in IP address dotted-decimal notation.
- ieee-mac-address
Specifies the 48-bit MAC address for the static ARP in the form aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff where aa, bb, cc, dd, ee and ff are hexadecimal numbers. Allowed values are any non-broadcast, non-multicast MAC and non-IEEE reserved MAC addresses.

Interface Service Access Point commands
sap
Syntax
sap sap-id [create]
no sap sap-id
Context
config>service>vprn>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command creates a Service Access Point (SAP) within a service. A SAP is a combination of port and encapsulation parameters that identify the service access point on the interface and within the 7210 SAS. Each SAP must be unique.
All SAPs must be explicitly created. If no SAPs are created within a service or on an IP interface, a SAP does not exist on that object.
Enter an existing SAP without the create keyword to edit SAP parameters. The SAP is owned by the service in which it was created.
A SAP can be associated with only a single service. A SAP can be defined only on a port that has been configured as an access port using the config interface port-type port-id mode access command.
If a port is shut down, all SAPs on that port become operationally down. When a service is shut down, SAPs for the service are not displayed as operationally down, although all traffic traversing the service is discarded. The operational state of a SAP is relative to the operational state of the port on which the SAP is defined.
The no form of this command deletes the SAP with the specified port. When a SAP is deleted, all configuration parameters for the SAP are also deleted.
Special Cases
- VPRN
A VPRN SAP must be defined on an Ethernet interface.
Parameters
- sap-id
Specifies the physical port identifier portion of the SAP definition. See Common CLI command descriptions for command syntax.
- port-id
Specifies the physical port ID in the slot/mda/port format.
If the card in the slot has Media Dependent Adapters (MDAs) installed, the port-id must be in the slot_number/MDA_number/port_number format.
The port-id must reference a valid port type. The port must be configured as an access port.
- create

Interface anti-spoofing commands
anti-spoof
Syntax
anti-spoof {ip | mac | ip-mac | nh-mac}
no anti-spoof-type
Context
config>service>vprn>if>sap
config>service>vprn>sub-if>grp-if>sap
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command enables anti-spoof filtering and optionally changes the anti-spoof matching type for the interface.
The type of anti-spoof filtering defines what information in the incoming packet is used to generate the criteria to look up an entry in the anti-spoof filter table. The parameter type defines the anti-spoof filter type enforced by the SAP when anti-spoof filtering is enabled.
The following are the default filter types:
non-Ethernet encapsulation default anti-spoof filter type
When enabled on a non-Ethernet encapsulated SAP, the anti-spoof filter default type is ip.
Ethernet encapsulated default anti-spoof filter type
When enabled on an Ethernet encapsulated SAP, the anti-spoof default type is ip-mac.
default anti-spoof filter state
By default, anti-spoof filtering is disabled on the SAP.
The no form of this command disables anti-spoof filtering on the SAP.
Parameters
- ip
Keyword to specify that SAP anti-spoof filtering uses only the source IP address in its lookup. If a static host exists on the SAP without an IP address specified, the anti-spoof type ip command fails.
- mac
Keyword to specify that SAP anti-spoof filtering uses only the source MAC address in its lookup. Setting the anti-spoof filter type to mac is not allowed on non-Ethernet encapsulated SAPs. If a static host exists on the SAP without a specified MAC address, the anti-spoof type mac command fails. The anti-spoof type mac command also fails if the SAP does not support Ethernet encapsulation.
- ip-mac
Keyword to specify that SAP anti-spoof filtering uses both the source IP address and the source MAC address in its lookup. If a static host exists on the SAP without both the IP address and MAC address specified, the anti-spoof type ip-mac command fails. This is also true if the default anti-spoof filter type of the SAP is ip-mac and the default is not overridden. The anti-spoof type ip-mac command also fails if the SAP does not support Ethernet encapsulation.
- nh-mac
Keyword to specify that the ingress anti-spoof is based on the source MAC address and the egress anti-spoof is based on the nh-ip-address.

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures populating static and dynamic hosts into the system ARP cache. When enabled, the host IP address and MAC address are placed in the system ARP cache as a managed entry.
Static hosts must be defined on the interface using the host command. Dynamic hosts are enabled on the system through enabling lease-populate in the IP interface DHCP context. In the event that both a static host and a dynamic host share the same IP and MAC address, the system ARP cache retains the host information until both the static and dynamic information are removed. Both static and dynamic hosts override static ARP entries. Static ARP entries are marked as inactive when they conflict with static or dynamic hosts and are repopulated when all static and dynamic host information for the IP address are removed. Because static ARP entries are not possible when static subscriber hosts are defined or when DHCP lease state table population is enabled, conflict between static ARP entries and the arp-populate function is not an issue.
The arp-populate command fails if an existing static subscriber host on the SAP does not have both MAC and IP addresses specified.
When the arp-populate command is enabled, creating a static subscriber host on the SAP without both an IP address and MAC address fails.
The arp-populate command can be enabled on only VPRN interfaces supporting Ethernet encapsulation.
The no form of this command disables ARP cache population functions for static and dynamic hosts on the interface. All static and dynamic host information in the system ARP cache are removed. Any existing static ARP entries previously inactive because of static or dynamic hosts are populated in the system ARP cache.
When arp-populate is enabled, the system does not send out ARP requests for hosts that are not in the ARP cache. Only statically configured and DHCP learned hosts are reachable through an IP interface with the arp-populate command enabled.
Default
no arp-populate
arp-timeout
Syntax

Context
config>service>vprn>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures the minimum time in seconds an ARP entry learned on the IP interface is stored in the ARP table. ARP entries are automatically refreshed when an ARP request or gratuitous ARP is seen from an IP host; otherwise, the ARP entry is aged from the ARP table. If arp-timeout is set to a value of zero seconds, ARP aging is disabled.
The no form of this command reverts to the default value.
Default
14400 seconds
Parameters
- seconds
Specifies the minimum number of seconds a learned ARP entry is stored in the ARP table, expressed as a decimal integer. A value of zero specifies that the timer is inoperative and learned ARP entries are not aged.
delayed-enable
Syntax
delayed-enable seconds [init-only]
no delayed-enable
Context
config>service>vprn>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command delays making the interface operational by the specified number of seconds.
In environments with many subscribers, it can take time to synchronize the subscriber state between peers when the subscriber interface is enabled (for example, after a reboot). To ensure that the state has time to be synchronized, the delayed-enable timer can be specified. The optional init-only parameter specifies to use the delayed-enable timer only after a reboot.
Default
no delayed-enable
Parameters
- seconds
Specifies the number of seconds to delay before the interface is operational.
- init-only
Keyword that delays the initialization of the subscriber interface to give the system time to complete necessary tasks, such as allowing routing protocols to converge or MCS to synchronize the subscriber information. The delay occurs only immediately after a reboot.

Context
config>service>vprn>if>sap
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command creates a static host for the SAP. Applications within the system that make use of static host entries include anti-spoof and source MAC population into the VPLS forwarding database.
Multiple static hosts can be defined on the SAP. Each host is identified by a source IP address, a source MAC address, or both a source IP and source MAC address. When anti-spoof is enabled on the SAP, the host information is populated into the SAP anti-spoof table, allowing ingress packets that match the entry to access the SAP. When the MAC address exists in the host definition, the MAC address is populated into the VPLS forwarding database and associates it with the SAP. The static host definition overrides static MAC entries using the same MAC and prevents dynamic learning of the MAC on another interface.
Defining a static host identical to an existing static host has no effect and does not generate a log or error message.
Every static host definition must have at least one address defined: IP or MAC.
Static hosts may exist on the SAP even with anti-spoof and arp-populate (VPRN) features disabled. When enabled, each feature has different requirements for static hosts.
The no form of this command removes a static entry from the system. The specified ip address and mac address must exactly match the IP and MAC addresses of the host as defined when it was created. When a static host is removed from the SAP, the affect of its removal on the anti-spoof filter, ARP cache, or the VPLS forwarding database is also evaluated.
Parameters
- anti-spoof
Keyword that specifies to use static and dynamic host information to populate entries into an anti-spoof filter table. The anti-spoof filter entries generated are of the same type as specified in the anti-spoof type parameter. If the SAP anti-spoof filter is defined as mac, each static host definition must specify a MAC address. If the SAP anti-spoof filter is defined as ip, each static host definition must specify an IP address. If the SAP anti-spoof filter is defined as ip-mac, each static host definition must specify both an IP address and MAC address. If the definition of a static host is attempted without addresses specified for the enabled anti-spoof filter, the static host definition fails.
- arp-populate
Keyword that specifies to use static and dynamic host information to populate entries into the system ARP cache. This is only available on the VPRN service SAPs. Both a MAC address and IP address are required to populate an ARP entry in the system. If the definition of a static host is attempted without both a MAC and IP address specified when arp-populate is enabled, the static host definition fails.
- fdb-populate
Keyword that is an implicit feature and uses the static host definition as a static MAC in the VPLS forwarding database. It cannot be enabled or disabled and has no effect on the ability to create static hosts without a MAC address specified. When a MAC address is specified for a static host, it is automatically populated into the VPLS forwarding database associated with the SAP on which the host is created. The static host MAC address overrides static MAC entries that use the same MAC and prevent dynamic learning of the MAC on another interface. Existing static MAC entries with the same MAC address as a static host are marked as inactive but not deleted. If all static hosts are removed from the SAP, the static MAC may be populated. New static MAC definitions for the VPLS instance may be created while a static host exists associated with the static MAC address.
- ip ip-address
Optional parameter that specifies a static host. The IP address must be specified for anti-spoof ip and anti-spoof ip-mac commands. Only one static host can be configured on the SAP with a specified IP address. The following rules apply to configuring static hosts using an IP address.
Only one static host can be defined using a specific IP address.
Defining a static host with the same IP address as a previous static host overwrites the previous static host.
If a static host has an IP address assigned, the MAC address for the host is optional (depending on the features enabled on the SAP).
- mac mac-address
Optional parameter that specifies a static host. The MAC address must be specified for anti-spoof ip and anti-spoof ip-mac. Multiple static hosts may be configured with the same MAC address if each definition is distinguished by a unique IP address. The following rules apply to configuring static hosts using a MAC address:
Multiple static hosts can share the same MAC address.
Executing the host command with the same MAC address but a different IP address as an existing static host creates a new static host.
If a static host has a MAC address assigned, the IP address for the host is optional (depending on the features enabled on the SAP).
- subscriber sub-ident-string
Optional parameter that specifies an existing subscriber identification profile to be associated with the static subscriber host. The subscriber identification profile is configured using the config>subscr-mgmt>sub-ident-policy context. The subscriber information is used by the VPRN SAP arp-reply-agent to determine the correct handling of received ARP requests from subscribers.
For VPRN SAPs with arp-reply-agent enabled with the optional sub-ident parameter, the static subscriber host sub-ident-string is used to determine whether an ARP request received on the SAP is sourced from a host belonging to the same subscriber as the destination host. When both the destination and source hosts from the ARP request are known on the SAP and the subscriber identifications do not match, the ARP request may be forwarded to the rest of the VPRN destinations.
If the static subscriber host sub-ident-string is not defined, the host is not considered to belong to the same subscriber as another host on the SAP.
If source or destination host is unknown, the hosts are not considered to belong to the same subscriber. ARP messages from unknown hosts are subject to anti-spoof filtering rules applied at the SAP.
If sub-ident is not enabled on the SAP arp-reply-agent, subscriber identification matching is not performed on ARP requests received on the SAP.
ARP requests are never forwarded back to the same SAP or within the receiving SAP split horizon group.
- sub-profile sub-profile-name
Optional parameter that specifies an existing subscriber profile name to be associated with the static subscriber host. The subscriber profile is configured in the config>subscr-mgmt>sub-profile context.
- sla-profile sla-profile-name
Optional parameter that specifies an existing SLA profile name to be associated with the static subscriber host. The SLA profile is configured in the config>subscr-mgmt>sla-profile context.

interleave
Syntax

no interleave
Context
config>service>vprn>if>sap>frame-relay>frf.12
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command enables interleaving of high priority frames and low-priority frame fragments within a FR SAP using FRF.12 end-to-end fragmentation.
When this option is enabled, only frames of the FR SAP non-expedited forwarding class queues are subject to fragmentation. The frames of the FR SAP expedited queues are interleaved, with no fragmentation header among the fragmented frames. This provides behavior similar to MLPPP Link Fragment Interleaving (LFI).
When this option is disabled, frames of all the FR SAP forwarding class queues are subject to fragmentation. However, the fragmentation header is not included when the frame size is smaller than the user-configured fragmentation size. In this mode, the SAP transmits all fragments of a frame before sending the next full or fragmented frame.
The receive direction of the FR SAP supports both modes of operation concurrently, with and without fragment interleaving.
The no form of this command reverts to the default value.
Default
no interleave

agg-rate-limit
Syntax
agg-rate-limit agg-rate
no agg-rate-limit
Context
config>service>vprn>if>sap>egress
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command defines a maximum total rate for all egress queues on a service SAP.
The port scheduler mode should be set to ‟sap-based” scheduling mode before using this command. The egress port scheduler enforces the aggregate queue rate for the SAP as it distributes its bandwidth to all the SAPs configured on the port. The port scheduler stops distributing bandwidth to member queues when it has detected that the aggregate rate limit has been reached.
A SAP aggregate scheduler is created for each instance of the SAP queues created on each of the member ports of the LAG. For a LAG, the port scheduler mode configured for the primary port is used for all the member ports of the LAG.
The scheduler mode is specified by the scheduler-mode command. To implement the agg-rate-limit, the scheduler mode must be specified as ‟sap-based”. See the 7210 SAS-Mxp, R6, R12, S, Sx, T Interface Configuration Guide for more information about the scheduler-mode command.
The no form of this command removes the aggregate rate limit from the SAP or multi-service site.
Parameters
- agg-rate
Specifies the aggregate rate, in kilobits-per-second, that the queues on the SAP or MSS can operate.
aggregate-meter-rate
Syntax
aggregate-meter-rate rate-in-kbps [burst burst-in-kbits] [enable-stats]
no aggregate-meter-rate
Context
config>service>vprn>if>sap>egress
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command associates a set of two counters to count total forwarded packets and octets and total dropped packets and octets. When the counter is enabled, the number of resources required increases by twice the number of resources taken up when counter is not used. If the enable-stats keyword is specified during the creation of the meter, the counter is allocated by the software, if available. To free up the counter and relinquish its use, the user can use the no aggregate-meter-rate command, and then recreate the meter using the aggregate-meter-rate command.
If egress rrame-based accounting is used, the SAP egress aggregate meter rate accounts for the Ethernet frame overhead. The system accounts for 12 bytes of IFG and 8 bytes of start delimiter. Frame-based counting does not affect the count of octets maintained by the counter, if it is in use.
Before enabling this command for a SAP, resources must be allocated to this feature from the egress internal TCAM resource pool using the configure system resource-profile egress-internal-tcam egress-sap-aggregate-meter command. See the 7210 SAS-Mxp, R6, R12, S, Sx, T Basic System Configuration Guide for more information.
The egress aggregate meter is not FC aware. The forward and drop decisions are made based on the order the packets are sent out of the SAP by the egress port scheduler.
The no form of this command removes the egress aggregate policer from use.
Default
no aggregate-meter-rate
Parameters
- rate-in-kbps
Specifies the rate in kilobits per second.
- burst-in-kbits
Specifies the burst size for the policer in kilobits. The burst size cannot be configured without configuring the rate.
- enable-stats
Keyword to specify whether the counter that counts forwarded and dropped packets must be allocated.

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command associates an IP filter policy with an ingress or egress SAP or IP interface. Filter policies control the forwarding and dropping of packets based on IP matching criteria.
The filter command is used to associate a filter policy that has a specified ip-filter-id with an ingress or egress SAP. The ip-filter-id must already be defined before the filter command is executed. If the filter policy does not exist, the operation fails and an error message is returned.
In general, filters applied to SAPs (ingress or egress) apply to all packets on the SAP. One exception is non-IP packets are not applied to IP match criteria, so the default action in the filter policy applies to these packets.
The no form of this command removes any configured filter ID association with the SAP or IP interface. The filter ID is not removed from the system unless the scope of the created filter is set to local.
Parameters
- ip ip-filter-id
Specifies the IP filter policy. The filter ID must already exist within the created IP filters.
- ipv6 ipv6-filter-id
Specifies the IPv6 filter policy. The filter ID must already exist within the created IPv6 filters.
- mac mac-filter-id
Specifies the MAC filter policy. The specified filter ID must already exist within the created MAC filters. The filter policy must already exist within the created MAC filters.

This command associates a QoS policy with an ingress or egress SAP or IP interface.
QoS ingress and egress policies are important for the enforcement of SLA agreements. The policy ID must be defined before associating the policy with a SAP or IP interface. If the policy-id does not exist, an error is returned.
The qos command associates both ingress and egress QoS policies. The qos command only allows ingress policies to be associated on SAP or IP interface ingress, and only allows egress policies on SAP or IP interface egress. Attempts to associate a QoS policy of the wrong type returns an error.
Only one ingress and one egress QoS policy can be associated with a SAP or IP interface at one time. Attempts to associate a second policy of the same or different type replaces the earlier one with the new policy.
On the 7210 SAS-R6 and 7210 SAS-R12 (ingress), using the enable-table-classification keyword enables the use of IP DSCP tables to assign FC and profile on a per-SAP ingress basis. The match-criteria configured in the service ingress policy, which require CAM resources, are ignored. Only meters from the service ingress policy are used (and the meters still require CAM resources). The IP DSCP classification policy configured in the SAP ingress policy is used to assign FC and profile. The default FC is assigned from the SAP ingress policy.
By default, no specific QoS policy is associated with the SAP or IP interface for ingress or egress, so the default QoS policy is used.
The no form of this command removes the QoS policy association from the SAP or IP interface, and the QoS policy reverts to the default value.
Parameters
- policy-id
Specifies the ingress or egress policy ID to associate with SAP or IP interface on ingress or egress. The policy ID must already exist.
- enable-table-classification
Keyword that enables the use of table-based classification instead of CAM-based classification at SAP ingress. The FC and profile are taken from the IP DSCP classification policy configured in the ingress policy, along with the meters from the SAP ingress policy. Match-criteria entries in the SAP ingress policy are ignored.

Description
This command configures the SAP aggregate policer. The rate of the SAP aggregate policer must be specified by the user. The user can optionally specify the burst size for the SAP aggregate policer. The aggregate policer monitors the traffic on different FCs and determines the destination of the packet. The packet is either forwarded to an identified profile or dropped.
The following table lists information about the final disposition of the packet based on the operating rate of the per-FC policer and the per-SAP aggregate policer.

When the SAP aggregate policer is configured, the per-FC policer can be configured only in ‟trtcm2” mode (RFC 4115).
The SAP ingress meter counters increment the packet or octet counts based on the final disposition of the packet.
If ingress frame-based accounting is used, the SAP aggregate meter rate accounts for the Ethernet frame overhead. The system accounts for 12 bytes of IFG and 8 bytes of start delimiter.
The no form of this command removes the aggregate policer from use.
Default
no aggregate-meter-rate
Parameters
- rate-in-kbps
Specifies the rate in kilobits per second.
- burst burst-in-kilobits
Specifies the burst size for the policer in kilobits. The burst size cannot be configured without configuring the rate.

Description
This command, within the SAP ingress contexts, enables the context for specific overrides to a specific meter created on the SAP through a sap-ingress QoS policies.
The no form of this command is used to remove any existing overrides for the specified meter-id.
Parameters
- meter-id
Specifies the meter ID. The specified meter-id must exist within the SAP ingress QoS policy applied to the SAP. If the meter is not currently used by any forwarding class or forwarding type mappings, the meter does noty exist on the SAP. This does not preclude creating an override context for the meter-id.
- create

Context
config>service>vprn>if>sap>ingress>meter-override>meter
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command overrides specific attributes of the specified meter adaptation rule parameters. The adaptation rule controls the method used by the system to derive the operational CIR and PIR settings when the meter is provisioned in hardware. For the CIR and PIR parameters individually, the system attempts to find the best operational rate depending on the defined constraint.
The no form of this command removes any explicitly defined constraints used to derive the operational CIR and PIR created by the application of the policy. When a specific adaptation-rule is removed, the default constraints for rate and cir apply.
Default
no adaptation-rule
Parameters
- pir
Keyword that defines the constraints enforced when adapting the PIR rate defined within the meter-override meter command. The pir keyword requires a qualifier that defines the constraint used when deriving the operational PIR for the queue. When the meter-override command is not specified, the default applies.
When the meter mode in use is ‟trtcm2,” this parameter is interpreted as EIR value. See the 7210 SAS-Mxp, R6, R12, S, Sx, T Quality of Service Guide for a description and relevant notes for meter modes.
- cir
Keyword that defines the constraints enforced when adapting the CIR rate defined within the meter-override meter command. The cir parameter requires a qualifier that defines the constraint used when deriving the operational CIR for the queue. When the cir parameter is not specified, the default constraint applies.
- adaptation-rule
Specifies the criteria to use to compute the operational CIR and PIR values for this meter, while maintaining a minimum offset.

Context
config>service>vprn>if>sap>ingress>meter-override>meter
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command provides a mechanism to override the default CBS for the meter. The size parameter specifies the maximum burst size that can be transmitted by the source while still complying with the CIR. If the transmitted burst is lower than the CBS value, the packets are marked as in-profile by the meter to indicate that the traffic is complying with meter configured parameters.
The no form of this command reverts the CBS size to the default value.
Default
32 kbits
Parameters
- size
Specifies the value in either kbits, bytes, or kilobytes.

Description
This command is used to override the SAP ingress QoS policy configured rate parameters for the specified meter-id.
The no form of this command restores the policy defined metering and profiling rate to a meter.
Default
max
The max default specifies the amount of bandwidth in kilobits per second (thousand bits per second). The max value is mutually exclusive to the pir-rate value.
Parameters
- pir-rate
Specifies the administrative PIR rate, in kilobits, for the queue. When the rate command is executed, a valid PIR setting must be explicitly defined. When the rate command has not been executed, the default PIR of max is assumed. Fractional values are not allowed and must be entered as a positive integer.
When the meter mode is set to ‟trtcm2,” the PIR value is interpreted as the EIR value. See the 7210 SAS-Mxp, R6, R12, S, Sx, T Quality of Service Guide for more information.
The actual PIR rate is dependent on the queue adaptation-rule parameters and the hardware where the queue is provisioned.
- cir-rate
Specifies to override the default administrative CIR used by the queue. When the rate command is executed, a CIR setting is optional. When the rate command has not been executed or the cir parameter is not explicitly specified, the default CIR (0) is assumed. Fractional values are not allowed and must be entered as a positive integer.

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command creates a new customer site or edits an existing customer site using the customer-site-name parameter. A customer site is an anchor point to create an ingress and egress virtual scheduler hierarchy. When scheduler policies are defined for ingress and egress, the scheduler names contained in each policy are created according to the parameters defined in the policy. Multi-service customer sites exist for the sole purpose of creating a virtual scheduler hierarchy and making it available to queues on multiple SAPs.
The scheduler policy association with the customer site prevents the scheduler policy from being deleted until after the scheduler policy is removed from the customer site. The multi-service-site object generates a log message indicating that the association was deleted because of scheduler policy removal.
When the multi-service customer site is created, an ingress and egress scheduler policy association does not exist. This does not prevent the site from being assigned to a chassis slot or prevent service SAP assignment. After the site has been created, the ingress and egress scheduler policy associations can be assigned or removed at any time.
If customer-site-name already exists for the customer ID, the CLI context changes to that site name for the purpose of editing the site scheduler policies or assignment. Any modifications to an existing site affect all SAPs associated with the site. Changing a scheduler policy association may cause new schedulers to be created and existing queues on the SAPs to no longer be orphaned. Existing schedulers on the site may cease to exist, causing queues that rely on that scheduler to be orphaned.
If the customer-site-name does not exist, it is assumed that an attempt is being made to create a site of that name in the customer ID context. The success of the command execution depends on the following.
The maximum number of customer sites defined for the chassis slot has not been met.
The customer-site-name is valid.
The create keyword is included in the command line syntax (if the system requires it).
When the maximum number of customer sites is exceeded, a configuration error occurs; the command does not execute and the CLI context does not change.
If the customer-site-name is invalid, a syntax error occurs; the command does not execute and the CLI context does not change.
Parameters
- customer-site-name
Specifies a unique customer site name within the context of the customer.

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures the queue parameters cir-level and pir-weight. The system creates and associates a port-scheduler with every access port on the system. Every queue within a SAP is associated with the port scheduler available on the port on which the SAP is created. The port scheduler uses these parameters to apportion the bandwidth to all the queues competing for the available bandwidth.
Queues with the cir-level value set to 8 are treated differently by the software than other queues configured with different cir-level values. The PIR rate values configured for the cir-level 8 queues are ignored. Only CIR rate value is used and the PIR is set to the CIR value. In addition, when executing the no form of the rate command for a queue configured at cir-level 8, the default CIR (and PIR) value is set to 1.
The no form of this command sets the cir-level and pir-weight to default values.
Default
port-parent cir-level 1 pir-weight 1
Parameters
- cir-level cir-level
Specifies the priority of the queue with respect to other queues. The priority of the queue is used only in the CIR loop. Level "8" is the highest priority and level "1" is the lowest priority.
In the PIR loop, the priority of the queues cannot be configured. The system assigns the priority to the queues based on the cir-level associated with the queue.
- pir-weight pir-weight
Specifies the relative weight of the queue with respect to the other queues. The weight parameter is used only in the PIR loop. If a queue level parameter is set to ‟8,” the weight parameter is ignored by the system.

Description
This command overrides specific attributes of the specified queue PIR and CIR parameters. The PIR defines the maximum rate that the queue can transmit packets out an egress interface (for SAP egress queues). Defining a PIR does not necessarily guarantee that the queue can transmit at the intended rate. The actual rate sustained by the queue can be limited by oversubscription factors or available egress bandwidth.
The CIR defines the rate at which the system prioritizes the queue over other queues competing for the same bandwidth. In-profile packets are preferentially queued by the system at egress and at subsequent next-hop nodes where the packet can traverse. To be properly handled as in-profile or out-of-profile throughout the network, the packets must be marked accordingly for profiling at each hop.
The CIR can be used by the queue parent command cir-level and cir-weight parameters to define the amount of bandwidth considered to be committed for the child queue during bandwidth allocation by the parent scheduler.
The rate command can be executed at any time, altering the PIR and CIR rates for all queues created through the association of the SAP egress QoS policy with the queue-id.
The no form of this command reverts all queues created with the queue-id by association with the QoS policy to the default PIR and CIR parameters (max, 0).
Default
rate max cir 0
The max default specifies the amount of bandwidth in kilobits per second (thousand bits per second). The max value is mutually exclusive to the pir-rate value.
Parameters
- pir-rate
Specifies the administrative PIR rate, in kilobits, for the queue. When the rate command is executed, a valid PIR setting must be explicitly defined. When the rate command has not been executed, the default PIR of max is assumed. Fractional values are not allowed and must be entered as a positive integer.
The actual PIR rate is dependent on the queue adaptation-rule parameters and the actual hardware where the queue is provisioned.
- cir-rate
Specifies to override the default administrative CIR used by the queue. When the rate command is executed, a CIR setting is optional. When the rate command has not been executed or the cir parameter is not explicitly specified, the default CIR (0) is assumed.
Fractional values are not allowed and must be entered as a positive integer. The sum keyword specifies that the CIR be used as the summed CIR values of the children schedulers or queues.

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command overrides attributes of the specified scheduler name.
A scheduler defines a bandwidth control that limits each child (other schedulers and queues) associated with the scheduler. Scheduler objects are created within the hierarchical tiers of the policy. It is assumed that each scheduler created has queues or other schedulers defined as child associations. The scheduler can be a child (take bandwidth from a scheduler in a higher tier, except for schedulers created in tier 1). A total of 32 schedulers can be created within a single scheduler policy with no restriction on the distribution between the tiers.
Each scheduler must have a unique name within the context of the scheduler policy; however the same name can be reused in multiple scheduler policies. If scheduler-name already exists within the policy tier level (regardless of the inclusion of the create keyword), the context changes to that scheduler name for the purpose of editing the scheduler parameters. Modifications made to an existing scheduler are executed on all instantiated schedulers created through association with the policy of the edited scheduler. This can cause queues or schedulers to become orphaned (invalid parent association) and adversely affect the ability of the system to enforce service level agreements (SLAs).
If the scheduler-name exists within the policy on a different tier (regardless of the inclusion of the keyword create), an error occurs and the current CLI context does not change.
If the scheduler-name does not exist in this or another tier within the scheduler policy, it is assumed that an attempt is being made to create a scheduler of that name. The success of the command execution is dependent on the following.
The maximum number of schedulers has not been configured.
The provided scheduler-name is valid.
The create keyword is entered with the command if the system is configured to require it (enabled in the environment create command).
When the maximum number of schedulers has been exceeded on the policy, a configuration error occurs and the command does not execute nor does the CLI context change. If the provided scheduler-name is invalid, a name syntax error occur, the command does not execute, and the CLI context does not change.
Parameters
- scheduler-name
Specifies the name of the scheduler.
- create
Optional keyword that explicitly specifies that it is acceptable to create a scheduler with the specified scheduler-name. If the create keyword is omitted, scheduler-name is not created when the system environment variable create is set to true. This safeguard is intended to avoid accidental creation of system objects (such as schedulers) while attempting to edit an object with a mistyped name or ID. The keyword has no effect when the object already exists.
rate
Syntax
rate pir-rate [cir cir-rate]
no rate
Context
config>service>vprn>if>sap>egress>sched-override>scheduler
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command overrides attributes of the specified scheduler rate. The rate command defines the maximum bandwidth that the scheduler can offer its child queues or schedulers. The maximum rate is limited to the amount of bandwidth the scheduler can receive from its parent scheduler. If the scheduler has no parent, the maximum rate is assumed to be the amount available to the scheduler. When a parent is associated with the scheduler, the CIR parameter provides the amount of bandwidth to be considered during the parent scheduler ‟within CIR” distribution phase.
The actual operating rate of the scheduler is limited by bandwidth constraints other than its maximum rate. The parent scheduler may not have the available bandwidth to meet the scheduler needs, or the bandwidth available to the parent scheduler could be allocated to other child schedulers or child queues on the parent based on higher priority. The children of the scheduler may not need the maximum rate available to the scheduler because of insufficient offered load or limits to their own maximum rates.
When a scheduler is defined without specifying a rate, the default rate is max. If the scheduler is a root scheduler (no parent defined), the default maximum rate must be changed to an explicit value. Without this explicit value, the scheduler assumes that an infinite amount of bandwidth is available and allows all child queues and schedulers to operate at their maximum rates.
The no form of this command reverts all queues created with this queue-id by association with the QoS policy to the default PIR and CIR parameters.
Parameters
- pir-rate
Specifies the multiplier used to determine the PIR rate at which the queue operates. A value of 0 to 100000000 or the keyword max or sum is accepted. Any other value results in an error without modifying the current PIR rate.
To calculate the actual PIR rate, the rate described by the queue rate is multiplied by the pir-rate.
The SAP ingress context for PIR is independent of the defined forwarding class (fc) for the queue. The default pir and definable range is identical for each class. The PIR in effect for a queue defines the maximum rate at which the queue is allowed to forward packets in a specified second, therefore shaping the queue output.
The PIR parameter for SAP ingress queues does not have a negation (no) function. To revert the queue PIR rate to the default value, that value must be specified as the PIR value.
- cir cir-rate
Specifies a step-multiplier value that specifies the multiplier used to determine the CIR rate at which the queue operates. A value of 0 to 250 or the max keyword is accepted. Any other value results in an error without modifying the current CIR rate.
To calculate the actual CIR rate, the rate described by the rate pir pir-rate is multiplied by the cir cir-rate. If the cir is set to max, the CIR rate is set to infinity.
The SAP ingress context for CIR is dependent on the defined forwarding class (fc) for the queue. The default CIR and definable range is different for each class. The CIR in effect for a queue defines both its profile (in or out) marking level as well as the relative importance compared to other queues for scheduling purposes during congestion periods.

Description
This command enables and disables the use of IP DSCP table-based classification to assign FC and profile on a per-interface ingress basis.
The match-criteria configured in the service ingress policy, which require CAM resources, are ignored. Only meters from the service ingress policy are used (and the meters still require CAM resources). If an IP DSCP classification policy is configured in the VPLS SAP ingress policy, it is not used to assign FC and profile.
The no form of this command disables table-based classification. When disabled, the IP ingress packets within a VPLS service attached to the IP interface use the SAP ingress QoS policy applied to the virtual port used by the packets, when defined.

Description
This command specifies an IP DSCP classification policy that is applied to all ingress packets entering the VPLS service. The DSCP classification policy overrides existing SAP ingress QoS policies applied to SAPs for packets associated with the routing IP interface. The routed override QoS policy is optional and when it is not defined or it is removed, the IP routed packets use the existing SAP ingress QoS policy configured on the VPLS virtual port.
The no form of this command removes the IP DSCP classification policy from the ingress IP interface. When removed, the IP ingress routed packets within a VPLS service attached to the IP interface use the SAP ingress QoS policy applied to the virtual port used by the packets, when defined.

config>service>ies>if>vpls>ingress
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command specifies an IP filter ID that is applied to all ingress packets entering the VPLS service. The filter overrides the existing ingress IP filter applied to SAPs or SDP bindings for packets associated with the routing IP interface. The override filter is optional and if not defined or removed, the IP routed packets use the existing ingress IP filter on the VPLS virtual port.
The no form of this command is used to remove the IP routed override filter from the ingress IP interface. When removed, the IP ingress routed packets within a VPLS service attached to the IP interface use the IP ingress filter applied to the packets virtual port when defined.
Parameters
- ip-filter-id
Specifies the ID for the IP filter policy. Allowed values are integers that correspond to a previously created IP filter policy in the configure>filter>ip-filter context.

vrrp
Syntax
vrrp virtual-router-id [owner]
no vrrp virtual-router-id
Context
config>service>vprn>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command creates or edits a Virtual Router ID (VRID) on the service IP interface. A VRID is internally represented in conjunction with the IP interface name. This allows the VRID to be used on multiple IP interfaces while representing different virtual router instances.
Two VRRP nodes can be defined on an IP interface. One, both, or none may be defined as owner. The nodal context of vrrp virtual-router-id is used to define the configuration parameters for the VRID.
The no form of this command removes the specified VRID from the IP interface. This terminates VRRP participation for the virtual router and deletes all references to the VRID. The VRID does not need to be shut down to remove the virtual router instance.
Parameters
- virtual-router-id
Specifies a new virtual router ID or one that can be modified on the IP interface.
- owner
Keyword that defines the virtual router instance as an owner.
authentication-key

config>service>vprn>if>vrrp
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command assigns a simple text password authentication key to generate master VRRP advertisement messages and validate received VRRP advertisement messages.
The authentication-key command is one of the few commands not affected by the presence of the owner keyword. If simple text password authentication is not required, this command is not required. If the command is re-executed with a different password key defined, the new key will be used immediately. If a no authentication-key command is executed, the password authentication key reverts to the default value. The authentication-key command may be executed at any time, altering the simple text password used when authentication-key password authentication method is used by the virtual router instance. The authentication-type password command does not need to be executed before defining the authentication-key command.
To change the current in-use password key on multiple virtual router instances:
identify the current master
shut down the virtual router instance on all backups
execute the authentication-key command on the master to change the password key
execute the authentication-key command and no shutdown command on each backup key
The no form of this command reverts to the default value of the key.
Parameters
- authentication-key
Specifies the simple text password used when VRRP Authentication Type 1 is enabled on the virtual router instance. Type 1 uses a string eight octets long that is inserted into all transmitted VRRP advertisement messages and compared against all received VRRP advertisement messages. The authentication data fields are used to transmit the key.
The authentication-key parameter is expressed as a string consisting of up to eight alpha-numeric characters. Spaces must be contained in quotation marks ( ‟ ” ). The quotation marks are not considered part of the string.
The string is case-sensitive and is left-justified in the VRRP advertisement message authentication data fields. The first field contains the first four characters with the first octet (starting with IETF RFC bit position 0) containing the first character. The second field holds the fifth through eighth characters. Any unspecified portion of the authentication data field is padded with the value 0 in the corresponding octet.
- hash-key
Specifies the hash key. The key can be any combination of ASCII characters up to 22 characters (encrypted). If spaces are used in the string, enclose the entire string in quotation marks (‟ ”).
This is useful when a user must configure the parameter, but, for security purposes, the actual unencrypted key value is not provided.
- hash
Specifies the key is entered in an encrypted form. If the hash parameter is not used, the key is assumed to be in a non-encrypted, clear text form. For security, all keys are stored in encrypted form in the configuration file with the hash parameter specified.
- hash2
Specifies the key is entered in a more complex encrypted form. If the hash2 parameter is not used, the less encrypted hash form is assumed.

Supported on all 7210 SAS platforms as described in this document
Description
This command allows the non-owner master to reply to ICMP echo requests directed at the virtual router instances IP addresses. The ping request can be received on any routed interface.
Ping must not have been disabled at the management security level (either on the parent IP interface or based on the ping source host address). When ping reply is not enabled, ICMP echo requests to non-owner master virtual IP addresses are silently discarded.
Non-owner backup virtual routers never respond to ICMP echo requests regardless of the setting of ping-reply configuration.
The ping-reply command is available only in the non-owner vrrp virtual-router-id context. If the ping-reply command is not executed, ICMP echo requests to the virtual router instance IP addresses are silently discarded.
The no form of this command reverts the default operation of discarding all ICMP echo request messages destined for the non-owner virtual router instance IP addresses.

Parameters
- vrrp-policy-id
Specifies a VRRP priority control policy.
preempt
Syntax
preempt
no preempt
Context
config>service>vprn>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures the ability to override an existing non-owner master with the virtual router instance. Enabling preempt mode is recommended for correct operation of the base-priority and vrrp-policy-id definitions on the virtual router instance. If the virtual router cannot preempt an existing non-owner master, the affect of the dynamic changing of the in-use priority is greatly diminished.
The preempt command is available only in the non-owner vrrp virtual-router-id context. The owner may not be preempted because the priority of non-owners can never be higher than the owner. The owner always preempts all other virtual routers when it is available.
Non-owner virtual router instances only preempt when preempt is set and the current master has an in-use message priority value less than the virtual router instance in-use priority.
A master non-owner virtual router only allows itself to be preempted when the incoming VRRP advertisement message priority field value is one of the following:
creater than the virtual router in-use priority value
equal to the in-use priority value, and the source IP address (primary IP address) is greater than the virtual router instance primary IP address
The no form of this command prevents a non-owner virtual router instance from preempting another, less desirable, virtual router.
Default
preempt

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures a specific priority value for the virtual router instance. In conjunction with an optional policy command, the base priority is used to derive the in-use priority of the virtual router instance.
The policy command is available only in the non-owner vrrp virtual-router-id context. The priority of owner virtual router instances is permanently set to 255 and cannot be changed. For non-owner virtual router instances, if the priority command is not executed, the base priority is set to 100.
The no form of this command reverts to the default value.
Parameters
- base-priority
Specifies the base priority used by the virtual router instance. If a VRRP priority control policy is not also defined, the base priority is the in-use priority for the virtual router instance.

Description
This command sets the counter mode for the counters associated with SAP ingress meters or policers. A pair of counters is available with each meter. These counters count different events based on the counter mode value.
Execute the following sequence of commands on the specified SAP to ensure the correct statistics are collected when the counter mode is changed.
Execute the config service vprn interface sap no collect-stats command to disable writing of accounting records for the SAP.
Change the counter mode to the needed option by executing the config service vprn interface sap counter-mode {in-out-profile-count | forward-drop-count} command.
Execute the config service vprn interface sap collect-stats command to enable writing of accounting records for the SAP.
The no form of this command reverts to the default value.
Default
in-out-profile-count
Parameters
- in-out-profile-count
Specifies that one counter counts the total in-profile packets and octets received on ingress of a SAP, and another counts the total out-of-profile packets and octets received on ingress of a SAP. A packet is determined to be in-profile or out-of-profile based on the meter rate parameters configured. A packet is dropped by the policer if it exceeds the configured PIR rate. Dropped counts are not maintained in hardware when this mode is used. It is obtained by subtracting the sum of in-profile count and out-of-profile count from the total SAP ingress received count and displayed.
- forward-drop-count
Specifies that one counter counts the forwarded packets and octets received on ingress of a SAP and another counts the dropped packets. The forwarded count is the sum of in-profile and out-of-profile packets and octets received on SAP ingress. The dropped count is count of packets and octets dropped by the policer. A packet is determined to be in-profile or out-of-profile based on the meter rate parameters configured. A packet is dropped by the policer if it exceeds the configured PIR rate. The in-profile count and out-of-profile count is not individually available when operating in this mode.

Description
This command configures the advertising of inactive BGP routers to other BGP peers.
By default, BGP only advertises BGP routes to other BGP peers if a specified BGP route is chosen by the route table manager as the most preferred route within the system and is active in the forwarding plane. This command allows system administrators to advertise a BGP route even though it is not the most preferred route within the system for a specified destination.

Context
config>service>vprn>bgp
config>service>vprn>bgp>group
config>service>vprn>bgp>group>neighbor
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command sets the router ID in the BGP aggregator path attribute to zero when BGP aggregates routes. This prevents different routers within an AS from creating aggregate routes that contain different AS paths.
When BGP is aggregating routes, it adds the aggregator path attribute to the BGP update messages. By default, BGP adds the ASN and router ID to the aggregator path attribute.
When this command is enabled, BGP adds the router ID to the aggregator path attribute. This command is used at the group level to revert to the value defined under the global level, and is used at the neighbor level to revert to the value defined under the group level.
The no form of this command used at the global level reverts to the default, where BGP adds the ASN and router ID to the aggregator path attribute.
The no form of this command used at the group level reverts to the value defined at the group level.
The no form of this command used at the neighbor level reverts to the value defined at the group level.
Default

Context
config>service>vprn>bgp
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures how the Multi-Exit Discriminator (MED) path attribute is used in the BGP route selection process. The MED attribute is always used in the route selection process regardless of the peer AS that advertised the route. This parameter determines what MED value is inserted in the RIB-IN. If this parameter is not configured, only the MEDs of routes that have the same peer ASs are compared.
The no form of this command removes the parameter from the configuration.
Default
no always-compare-med
Parameters
- zero
Keyword to specify that for routes learned without a MED attribute that a zero (0) value is used in the MED comparison. The routes with the lowest metric are the most preferred.
- infinity
Keyword to specify that for routes learned without a MED attribute that a value of infinity (4294967295) is used in the MED comparison. This in effect makes these routes the least desirable.

This command creates a BGP peer/neighbor instance within the context of the BGP group.
This command can be issued repeatedly to create multiple peers and their associated configuration.
The no form of this command is used to remove the specified neighbor and the entire configuration associated with the neighbor. The neighbor must be administratively shut down before attempting to delete it. If the neighbor is not shut down, the command does not result in any action except a warning message on the console indicating that neighbor is still administratively up.
Parameters
- ip-address
Specifies the IP address of the BGP peer router in dotted-decimal notation.

Description
This command specifies the address family or families to be supported over BGP peerings in the base router. This command is additive so issuing the family command adds the specified address family to the list.
The no form of this command removes the specified address family from the associated BGP peerings. If an address family is not specified, the supported address family reverts back to the default.
Default
ipv4
Parameters
- ipv4
Keyword to provision support for IPv4 routing information.
- ipv6
Keyword to provision support for IPv6 routing information.

Description
This command configures the BGP hold time, expressed in seconds.
The BGP hold time specifies the maximum time BGP waits between successive messages (either keepalive or update) from its peer, before closing the connection. This configuration parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in group), or neighbor level (only applies to specified peer). The most specific value is used.
The strict option ensures that the negotiated hold time value is not set to a value less than the configured value.
Even though the 7210 SAS implementation allows setting the time separately, the configured keepalive timer is overridden by the hold-time value under the following circumstances.
If the specified hold-time value is less than the configured keepalive time, the operational keepalive time is set to a third of the hold-time; the configured keepalive time is not changed.
If the hold-time is set to zero, the operational value of the keepalive time is set to zero; the configured keepalive time is not changed. This means that the connection with the peer is up permanently, and no keepalive packets are sent to the peer.
The no form of this command used at the global level reverts to the default value.
The no form of this command used at the group level reverts to the value defined at the global level.
The no form of this command used at the neighbor level reverts to the value defined at the group level.
Default
90 seconds
Parameters
- seconds
Specifies the hold-time, in seconds, expressed as a decimal integer. A value of 0 indicates the connection to the peer is permanently up.
- strict
Keyword to specifies that the advertised BGP hold-time from the far-end BGP peer must be greater than or equal to the specified value.

Description
This command configures the BGP keepalive timer. A keepalive message is sent every time this timer expires.
This command can be set at three levels: global level (applies to all peers), group level (applies to all peers in peer-group), or neighbor level (only applies to specified peer). The most specific value is used.
The keepalive value is generally one-third of the interval. Even though the 7210 SAS implementation allows the keepalivevalue and the hold-time interval to be independently set, under the following circumstances, the configured keepalive value is overridden by the hold-time value.
If the specified keepalive value is greater than the configured hold-time, the specified value is ignored, and the keepalive is set to one third of the current hold-time value.
If the specified hold-time interval is less than the configured keepalive value, the keepalive value is reset to one-third of the specified hold-time interval.
If the hold-time interval is set to zero, the configured value of the keepalive value is ignored. This means that the connection with the peer is up permanently and no keepalive packets are sent to the peer.
The no form of this command used at the global level reverts to the default value.
The no form of this command used at the group level reverts to the value defined at the global level.
The no form of this command used at the neighbor level reverts to the value defined at the group level.

Description
This command configures the local IP address used by the group or neighbor when communicating with BGP peers.
Outgoing connections use the local-address as the source of the TCP connection when initiating connections with a peer.
When a local address is not specified, the 7210 SAS uses the system IP address when communicating with iBGP peers and uses the interface address for directly connected eBGP peers. This command is used at the neighbor level to revert to the value defined under the group level.
The router ID is used when communicating with iBGP peers and the interface address is used for directly connected eBGP peers.
The no form of this command removes the configured local-address for BGP.
The no form of this command used at the group level reverts to the value defined at the global level.
The no form of this command used at the neighbor level reverts to the value defined at the group level.
Default
no local-address
Parameters
- ip-address
Specifies the local address, expressed in dotted-decimal notation. Allowed values are a valid routable IP address on the router, either an interface or system IP address.

Description
This command configures a BGP virtual autonomous system (AS) number.
In addition to the AS number configured for BGP in the config>router>autonomous-system context, a virtual (local) AS number is configured.The virtual AS number is added to the as-path message before the router AS number makes the virtual AS the second AS in the as-path.
This configuration parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in peer-group), or neighbor level (only applies to specified peer). Therefore, by specifying this at each neighbor level, it is possible to have a separate AS number per eBGP session.
When a command is entered multiple times for the same AS, the last command entered is used in the configuration. The private keyword can be added or removed dynamically by reissuing the command.
Changing the local AS at the global level in an active BGP instance causes the BGP instance to restart with the new local AS number. Changing the local AS at the global level in an active BGP instance causes BGP to reestablish the peer relationships with all peers in the group with the new local AS number. Changing the local AS at the neighbor level in an active BGP instance causes BGP to reestablish the peer relationship with the new local AS number.
This is an optional command and can be used in the following example.
Example: Provider router P is moved from AS1 to AS2. The customer router that is connected to P, however, is configured to belong to AS1. To avoid reconfiguring the customer router, the local-as value on router P can be set to AS1. Therefore, router P adds AS1 to the as-path message for routes it advertises to the customer router.
The no form of this command used at the global level will remove any virtual AS number configured.
The no form of this command used at the group level reverts to the value defined at the global level.
The no form of this command used at the neighbor level reverts to the value defined at the group level.
Default
no local-as
Parameters
- as-number
Specifies the virtual AS number, expressed as a decimal integer.
- private
Specifies that the local AS is hidden in paths learned from the peering.

Description
This command configures the default value of the BGP local preference attribute if it is not already specified in incoming routes. This value is used if the BGP route arrives from a BGP peer without the local-preference integer set.
The specified value can be overridden by any value set via a route policy. This configuration parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in peer-group), or neighbor level (only applies to specified peer). The most specific value is used.
The no form of this command at the global level specifies that incoming routes with local preference set are not overridden, and routes arriving without local preference set are interpreted as if the route had a local preference value of 100.
The no form of this command used at the group level reverts to the value defined at the global level.
The no form of this command used at the neighbor level reverts to the value defined at the group level.
Default

Description
This command creates ranges of addresses on an Area Border Router (ABR) for the purpose of route summarization or suppression. When created, a range is configured to be advertised or not advertised into other areas. Multiple range commands may be used to summarize or hide different ranges. In the case of overlapping ranges, the most specific range command applies.
ABRs send summary link advertisements to describe routes to other areas. To minimize the number of advertisements that are flooded, you can summarize a range of IP addresses and send reachability information about these addresses in an LSA.
The no form of this command deletes the range advertisement or non-advertisement.
Default
no area-range
Special Cases
- NSSA Context
In the NSSA context, the option specifies that the range applies to external routes (via type-7 LSAs) learned within the NSSA when the routes are advertised to other areas as type-5 LSAs.
- Area Context
If this command is not entered under the NSSA context, the range applies to summary LSAs even if the area is an NSSA.
Parameters
- ipv6-prefix/prefix-length
Specifies the IP prefix in dotted-decimal notation for the range used by the ABR to advertise the area into another area.
- mask
Specifies the subnet mask for the range expressed as a decimal integer mask length or in dotted-decimal notation.
- advertise | not-advertise
Keywords that specify whether to advertise the summarized range of addresses to other areas.

Description
This command enables authentication and specifies the type of authentication to be used on the OSPF interface, virtual-link, and sham-link.
Both simple password and message-digest authentication are supported.
By default, authentication is not enabled on an interface.
The no form of this command disables authentication on the interface.
Default
no authentication
Parameters
- password
Keyword that enables simple password (plain text) authentication. If authentication is enabled and no authentication type is specified in the command, simple password authentication is enabled.
- message-digest
Keyword that enables message digest MD5 authentication in accordance with RFC1321. If this option is configured, at least one message-digest-key must be configured.

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command enables the use of bidirectional forwarding (BFD) to control the state of the associated protocol interface. By enabling BFD on a specific protocol interface, the state of the protocol interface is tied to the state of the BFD session between the local node and the remote node. The parameters used for the BFD are set using the BFD command under the IP interface.
BFD is not supported for IPv6 interfaces.
See the 7210 SAS-Mxp, R6, R12, S, Sx, T Router Configuration Guide for more information about the protocols and platforms that support BFD.
The no form of this command removes BFD from the associated IGP protocol adjacency.
Default
no bfd-enable
Parameters
- remain-down-on-failure
Keyword that forces adjacency down on BFD failure.

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures the time, in seconds, that OSPF waits before declaring a neighbor router down. If no hello packets are received from a neighbor for the duration of the dead interval, the router is assumed to be down. The minimum interval must be two times the hello interval.
The no form of this command reverts to the default value.
Default
40
Special Cases
- OSPF Interface
If the dead-interval configured applies to an interface, all nodes on the subnet must have the same dead interval.
- Virtual Like
If the dead-interval configured applies to a virtual link, the interval on both termination points of the virtual link must have the same dead interval.
- Sham-link
If the dead-interval configured applies to a sham-link, the interval on both endpoints of the sham-link must have the same dead interval.
Parameters
- seconds
Specifies the dead interval in seconds, expressed as a decimal integer.

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures the interval between OSPF hellos issued on the interface, virtual link, or sham-link.
The hello-interval, in combination with the dead-interval, is used to establish and maintain the adjacency. Use this parameter to edit the frequency that hello packets are sent.
Reducing the interval, in combination with a corresponding reduction in the associated dead-interval, allows for faster detection of link or router failures at the cost of higher processing costs.
The no form of this command reverts to the default value.
Default
hello-interval 10
Special Cases
- OSPF Interface
If the hello-interval configured applies to an interface, all nodes on the subnet must have the same hello interval.
- Virtual Link
If the hello-interval configured applies to a virtual link, the interval on both termination points of the virtual link must have the same hello interval.
- Sham Link
If the hello-interval configured applies to a sham-link, the interval on both endpoints of the sham-link must have the same hello interval
Parameters
- seconds
Specifies the hello interval in seconds, expressed as a decimal integer.

Syntax
interface-type {broadcast | point-to-point}
no interface-type
Context
config>service>vprn>ospf>area>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures the interface type to be either broadcast or point-to-point.
Use this command to set the interface type of an Ethernet link to point-to-point to avoid having to carry the broadcast adjacency maintenance overhead if the Ethernet link, provided the link is used as a point-to-point link.
If the interface type is not known at the time the interface is added to OSPF, and the subsequent IP interface is bound (or moved) to a different interface type, this command must be entered manually.
The no form of this command reverts to the default value.
Default
point-to-point — If the physical interface is SONET.
broadcast — If the physical interface is Ethernet or unknown.
Special Cases
- Virtual-Link
A virtual link is always regarded as a point-to-point interface and is not configurable.
Parameters
- broadcast
Keyword that configures the interface to maintain this link as a broadcast network. To significantly improve adjacency forming and network convergence, a network should be configured as point-to-point if only two routers are connected, even if the network is a broadcast media such as Ethernet.
- point-to-point
Keyword that configures the interface to maintain this link as a point-to-point link.

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures a message digest key when MD5 authentication is enabled on the interface, virtual-link, or sham-link. Multiple message digest keys can be configured. By default, no message digest keys are defined.
The no form of this command removes the message digest key identified by the key-id.
Parameters
- keyid
Specifies the key ID, expressed as a decimal integer.
- md5 key
Specifies the MD5 key. The key can be any alphanumeric string up to 16 characters.
- md5 hash-key
Specifies the MD5 hash key. The key can be any combination of ASCII characters up to 32 characters (encrypted). If spaces are used in the string, enclose the entire string in quotation marks (‟ ”).
This is useful when a user must configure the parameter, but, for security purposes, the actual unencrypted key value is not provided.
- hash
Keyword to specify that the key is entered in an encrypted form. If the hash parameter is not used, the key is assumed to be in a non-encrypted, clear text form. For security, all keys are stored in encrypted form in the configuration file, with the hash parameter specified.

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures an explicit route cost metric for the OSPF interface that overrides the metrics calculated based on the speed of the underlying link.
The no form of this command deletes the manually configured interface metric, so the interface uses the computed metric based on the reference-bandwidth command setting and the speed of the underlying link.
Default
no metric
Parameters
- metric
Specifies the metric to be applied to the interface, expressed as a decimal integer.
mtu
Syntax
mtu bytes
no mtu
Context
config>service>vprn>ospf>area>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures the OSPF packet size used on the interface.
If this command is not configured, OSPF derives the MTU value from the MTU configured (default or explicitly) in the config>port>ethernet context.
If this parameter is configured, the smaller value between the value configured here and the MTU configured (default or explicitly) in a previously mentioned context is used.
To determine the actual packet size, add 14 bytes for an Ethernet packet and 18 bytes for a tagged Ethernet packet to the size of the OSPF (IP) packet MTU configured using this command.
The no form of this command reverts to default value.
Default
no mtu
Parameters
- bytes
Specifies the MTU to be used by OSPF for this logical interface in bytes.
passive
Syntax
[no] passive
Context
config>service>vprn>ospf>area>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command adds the passive property to an OSPF interface.
By default, only interface addresses that are configured for OSPF are advertised as OSPF interfaces. The passive command allows an interface to be advertised as an OSPF interface without running the OSPF protocol.
While in passive mode, the interface ignores ingress OSPF protocol packets and does not transmit any OSPF protocol packets.
Service interfaces defined in the config>router>service-prefix context are passive. All other interfaces are not passive.
The no form of this command removes the passive property from the OSPF interface.
priority
Syntax
priority number
no priority
Context
config>service>vprn>ospf>area>if
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures the priority of the OSPF interface that is used in an election of the designated router on the subnet.
This command is used only when the interface is of type broadcast. The router with the highest priority interface becomes the designated router. A router with priority 0 is not eligible to be a designated router or backup designated router.
The no form of this command reverts to the default value.
Default
priority 1
Parameters
- number
Specifies the interface priority expressed as a decimal integer. A value of 0 indicates the router is not eligible to be the designated router or backup designated router on the interface subnet.

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command specifies the length of time, in seconds, that OSPF waits before retransmitting an unacknowledged Link State Advertisement (LSA) to an OSPF neighbor.
The value should be longer than the expected round trip delay between any two routers on the attached network. When the retransmit interval expires and no acknowledgment has been received, the LSA isretransmitted.
The no form of this command reverts to the default value.
Default
retransmit-interval 5
Parameters

nssa
Syntax
[no] nssa
Context
config>service>vprn>ospf>area
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures an OSPF Not So Stubby Area (NSSA) and adds or removes the NSSA designation from the area.
NSSAs are similar to stub areas in that no external routes are imported into the area from other OSPF areas. The major difference between a stub area and an NSSA is an NSSA has the capability to flood external routes that it learns throughout its area and via an ABR to the entire OSPF domain.
Existing virtual links of a non-stub or NSSA area are removed when the designation is changed to NSSA or stub.
An area can be designated as stub or NSSA but never both at the same time.
By default, an area is not configured as an NSSA area.
The no form of this command removes the NSSA designation and configuration context from the area.
Default
no nssa

Syntax
originate-default-route [type-7]
no originate-default-route
Context
config>service>vprn>ospf>area>nssa
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command enables the generation of a default route and its LSA type (3 or 7) into an NSSA by an NSSA Area Border Router (ABR).
When configuring an NSSA with no summaries, the ABR injects a type-3 LSA default route into the NSSA area. Some older implementations expect a type-7 LSA default route.
The no form of this command disables origination of a default route.
Default
no originate-default-route
Parameters
- type-7
Keyword that specifies a type-7 LSA should be used for the default route.
Configure this parameter to inject a type-7 LSA default route instead of the type-3 LSA into the NSSA configured with no summaries. To revert to a type-3 LSA, enter originate-default-route without the type-7 parameter.
redistribute-external
Syntax
[no] redistribute-external
Context
config>service>vprn>ospf>area>nssa
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command enables the redistribution of external routes into the NSSA or an NSSA ABR that is exporting the routes into non-NSSA areas.
NSSAs are similar to stub areas in that no external routes are imported into the area from other OSPF areas. The major difference between a stub area and an NSSA is that the NSSA has the capability to flood external routes that it learns (providing it is an ASBR) throughout its area and via an ABR to the entire OSPF domain.
The no form of this command disables the default behavior to automatically redistribute external routes into the NSSA area from the NSSA ABR.
Default
redistribute-external

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command enables sending summary (type-3) advertisements into a stub area or NSSA on an ABR.
This command is particularly useful to reduce the size of the routing and Link State Database (LSDB) tables within the stub or nssa area. By default, summary route advertisements are sent into the stub area or NSSA.
The no form of this command disables sending summary route advertisements and, for stub areas, only the default route is advertised by the ABR.
Default
summaries
stub
Syntax
[no] stub
Context
config>service>vprn>ospf>area
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures an OSPF stub area and adds or removes the stub designation from the area.
External routing information is not flooded into stub areas. All routers in the stub area must be configured with the stub command. An OSPF area cannot be both an NSSA and a stub area. Existing virtual links of a non-stub area or NSSA are removed when its designation is changed to NSSA or stub.
By default, an area is not a stub area.
The no form of this command removes the stub designation and configuration context from the area.
Default
no stub

Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures the metric used by the ABR for the default route into a stub area.
The default metric should be configured only on an ABR of a stub area. An ABR generates a default route if the area is a stub area.
The no form of this command reverts to the default value.
Default
default-metric 1
Parameters
- metric
Specifies the metric, expressed as a decimal integer, for the default route cost to be advertised into the stub area.
virtual-link
Syntax
[no] virtual-link router-id transit-area area-id
Context
config>service>vprn>ospf>area
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures a virtual link to connect ABRs to the backbone.
The backbone area (area 0.0.0.0) must be contiguous and all other areas must be connected to the backbone area. If it is not practical to connect an area to the backbone (see area 0.0.0.2 in OSPF areas), the area border routers (routers 1 and 2 in OSPF areas) must be connected via a virtual link. The two area border routers form a point-to-point like adjacency across the transit area (area 0.0.0.1 in OSPF areas). A virtual link can be configured only while in the area 0.0.0.0 context.
The OSPF backbone area, area 0.0.0.0, must be contiguous and all other areas must be connected to the backbone area. The backbone distributes routing information between areas. If it is not practical to connect an area to the backbone (see area 0.0.0.5 in the following figure), the area border routers (such as routers Y and Z) must be connected via a virtual link. The two area border routers form a point-to-point-like adjacency across the transit area (see area 0.0.0.4).
The router-id specified in this command must be associated with the virtual neighbor. The transit area cannot be a stub area or an NSSA.
The no form of this command deletes the virtual link.
Parameters
- router-id
Specifies the router ID of the virtual neighbor, in IP address dotted-decimal notation.
- transit-area area-id
Specifies the area ID for the transit area that links the backbone area with the area that has no physical connection with the backbone.
compatible-rfc1583
Syntax
[no] compatible-rfc1583
Context
config>service>vprn>ospf
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command enables OSPF summary and external route calculations in compliance with RFC1583 and earlier RFCs.
RFC1583 and earlier RFCs use a different method to calculate summary and external route costs. To avoid routing loops, all routers in an OSPF domain should perform the same calculation method.
Although it would be favorable to require all routers to run a more current compliance level, this command allows the router to use obsolete methods of calculation.
The no form of this command enables the post-RFC1583 method of summary and external route calculation.
Default
compatible-rfc1583
export
Syntax
export policy-name [policy-name…]
no export
Context
config>service>vprn>ospf
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command associates export route policies to determine which routes are exported from the route table to OSPF. Export polices are in effect only if OSPF is configured as an ASBR.
If no export policy is specified, non-OSPF routes are not exported from the routing table manager to OSPF.
If multiple policy names are specified, the policies are evaluated in the order they are specified. The first policy that matches is applied. If multiple export commands are issued, the last command entered overrides the previous command. A maximum of five policy names can be specified. The specified names must already be defined.
The no form of this command removes all policies from the configuration.
Default
no export
Parameters
- policy-name
The export route policy name. Allowed values are any string up to 32 characters composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, and so on), the entire string must be enclosed within double quotes.
external-db-overflow
Syntax
external-db-overflow limit seconds
no external-db-overflow
Context
config>service>vprn>ospf
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures limits on the number of non-default AS-external LSA entries that can be stored in the link-state database (LSDB) and specifies a wait timer before processing these after the limit is exceeded.
The limit value specifies the maximum number of non-default AS-external LSA entries that can be stored in the LSDB. Placing a limit on the non-default AS-external LSAs in the LSDB protects the router from receiving an excessive number of external routes that consume excessive memory or CPU resources. If the number of routes reach or exceed the limit, the table is in an overflow state. When in an overflow state, the router will not originate any new AS-external LSAs and withdraws all the self-originated non-default external LSAs.
The seconds value specifies the amount of time to wait after an overflow state before regenerating and processing non-default, AS-external LSAs. The waiting period acts like a dampening period, preventing the router from continuously running shortest path first (SPF) calculations caused by the excessive number of non-default, AS-external LSAs.
The external-db-overflow command must be set identically on all routers attached to any regular OSPF area. OSPF stub areas and NSSAs are excluded.
The no form of this command disables limiting the number of non-default, AS-external LSA entries.
Default
no external-db-overflow
Parameters
- limit
Specifies the maximum number of non-default, AS-external LSA entries that can be stored in the LSDB before going into an overflow state, expressed as a decimal integer.
- seconds
Specifies the number of seconds after entering an overflow state before attempting to process non-default AS-external LSAs, expressed as a decimal integer.

Supported on all 7210 SAS platforms as described in this document
Description
This command configures the preference for OSPF external routes.
A route can be learned by the router from different protocols, in which case the costs are not comparable. When this occurs, the preference is used to decide which route is used.
Different protocols should not be configured with the same preference. If this occurs, the tiebreaker is based on the default preference table, as shown in the following table.
| Route type | Preference | Configurable |

If multiple routes are learned with an identical preference using the same protocol, the lowest cost route is used. If multiple routes are learned with an identical preference using the same protocol and the costs (metrics) are equal, the decision of which route to use is determined by the configuration of the ecmp command in the config>router context
The no form of this command reverts to the default value.
Default
external-preference 150
Parameters
- preference
Specifies the preference for external routes expressed as a decimal integer (see Route preference defaults by route type).
ignore-dn-bit
Syntax
[no] ignore-dn-bit
Context

This command specifies whether to ignore the DN (down) bit for OSPF LSA packets for this instance of OSPF on the router. When enabled, the DN bit for OSPF LSA packets is ignored. When disabled, the DN bit is not ignored for OSPF LSA packets.
import
Syntax
import policy-name [policy-name...(up to 5 max)]
no import
Context
config>service>vprn>ospf
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command specifies the import route policy that determines which routes are accepted from peers. Route policies are configured in the config>router>policy-options context.
This configuration parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in peer-group), or neighbor level (only applies to specified peer). The most specific level is used.
When multiple policy names are specified, the policies are evaluated in the order they are specified. A maximum of five (5) policy names can be specified. The first policy that matches is applied.
When multiple import commands are issued, the last command entered overrides the previous command.
The no form of this command removes the policy association. To remove the association of all policies, use no import without arguments.
Default
no import
Parameters
- policy-name
Specifies the route policy name. Allowed values are any string up to 32 characters composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, and so on), the entire string must be enclosed within double quotes.
overload
Syntax
overload [timeout seconds]
no overload
Context
config>service>vprn>ospf
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command changes the overload state of the local router so that it appears to be overloaded. When overload is enabled, the router can participate in OSPF routing, but is not used for transit traffic. Traffic that is destined for directly attached interfaces continues to reach the router.
To put the IGP in an overload state, enter a timeout value. The IGP enters the overload state until the timeout timer expires or a no overload command is executed.
If the overload command is encountered during the execution of an command, this command takes precedence. This could occur as a result of a saved configuration file where both parameters are saved. When the file is saved by the system, the overload-on-boot command is saved after the overload command.
The no form of this command reverts to the default value. When the no overload command is executed, the overload state is terminated, regardless of the reason the protocol entered overload state.
Default
no overload
Parameters
- timeout seconds
Specifies the number of seconds to reset overloading.
overload-include-stub
Syntax

Supported on all 7210 SAS platforms as described in this document
Description
This command configures whether the OSPF stub networks should be advertised with a maximum metric value when the system goes into an overload state for any reason. When enabled, the system uses the maximum metric value. When this command is enabled and the router is in overload, all stub interfaces, including loopback and system interfaces, are advertised at the maximum metric.
Default
no overload-include-stub
overload-on-boot
Syntax
overload-on-boot [timeout seconds]
no overload
Context
config>service>vprn>ospf
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
When the router is in an overload state, the router is used only if there is no other router to reach the destination. This command configures the IGP upon bootup in the overload state until one of the following events occur:
the timeout timer expires
a manual override of the current overload state is entered with the no overload command
The no overload command does not affect the overload-on-boot function.
The no form of this command removes the overload-on-boot functionality from the configuration.
Default
no overload-on-boot
Parameters
- timeout seconds
Specifies the number of seconds to reset overloading.
preference
Syntax

no preference
Context
config>service>vprn>ospf
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures the preference for OSPF internal routes.
A route can be learned by the router from different protocols, in which case the costs are not comparable. When this occurs, the preference is used to decide to which route is used.
Different protocols should not be configured with the same preference. If this occurs, the tiebreaker is based on the default preference table, as listed in Route preference defaults by route type. If multiple routes are learned with an identical preference using the same protocol, the lowest cost route is used.
If multiple routes are learned with an identical preference using the same protocol and the costs (metrics) are equal, the decision of which route to use is determined by the configuration of the ecmp command in the config>router context.
The no form of this command reverts to the default value.
Default
preference 10
Parameters
- preference
Specifies the preference for internal routes, expressed as a decimal integer. Route preference defaults by route type lists the defaults for different route types.
reference-bandwidth
Syntax
reference-bandwidth bandwidth-in-kbps
no reference-bandwidth
Context
config>service>vprn>ospf
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command configures the reference bandwidth used to calculate the default costs of interfaces based on their underlying link speed.
The default interface cost is calculated as follows:
cost = reference - bandwidth bandwidth
The default reference bandwidth is 100,000,000 kb/s or 100 Gb/s; therefore, the default auto-cost metrics for various link speeds are as follows:
10 Mb/s link default cost of 10000
100 Mb/s link default cost of 1000
1 Gb/s link default cost of 100
10 Gb/s link default cost of 10
The reference-bandwidth command assigns a default cost to the interface based on the interface speed. To override this default cost on an interface, use the metric command in the config>router>ospf>area>interface ip-int-name context.
The no form of this command reverts the reference-bandwidth to the default value.
Default
reference-bandwidth 100000000
Parameters
- bandwidth-in-kbps
Specifies the reference bandwidth in kilobits per second, expressed as a decimal integer.

Description
This command configures OSPF timers. Timers control the delay between receipt of an LSA requiring an SPF calculation and the minimum time between successive SPF calculations.
Changing the timers affects CPU utilization and network reconvergence times. Lower values reduce convergence time but increase CPU utilization. Higher values reduce CPU utilization but increase reconvergence time.
spf-wait
Syntax
spf-wait max-spf-wait [spf-initial-wait [spf-second-wait]]
no spf-wait
Context
config>service>vprn>ospf>timers
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command defines the maximum interval between two consecutive SPF calculations. in milliseconds. Timers that determine when to initiate the first, second, and subsequent SPF calculations after a topology change occurs can be controlled with this command. Subsequent SPF runs (if required) occur at exponentially increasing intervals of the spf-second-wait interval. For example, if the spf-second-wait interval is 1000, the next SPF runs after 2000 milliseconds, and the next SPF runs after 4000 milliseconds, and so on, until it reaches the spf-wait value. The SPF interval stays at the spf-wait value until there are no more SPF runs scheduled in that interval. After a full interval without any SPF runs, the SPF interval drops back to spf-initial-wait.
The timer must be entered in increments of 100 milliseconds. Values entered that do not match this requirement are rejected.
The no form of this command reverts to the default value.
Default
no spf-wait
Parameters
- max-spf-wait
Specifies the maximum interval, in milliseconds, between two consecutive SPF calculations.
- spf-initial-wait
Specifies the initial SPF calculation delay, in milliseconds, after a topology change.
- spf-second-wait
Specifies the hold time, in milliseconds, between the first and second SPF calculation.

Description
This command displays BGP neighbor information. This command can be entered with or without parameters. When this command is issued without parameters, information about all BGP peers displays.
When the command is issued with a specific IP address or ASN, only information for that specific peer or peers with the same AS is displayed.
When either received-routes or advertised-routes is specified, the routes received from or sent to the specified peer is listed (see second output example). This information is not available by SNMP.
When either history or suppressed is specified, the routes learned from those peers that either have a history or are suppressed (respectively) are listed.
The ‟State” field displays the BGP peer protocol state. In additional to the standard protocol states, this field can also display the ‟Disabled” operational state, which indicates the peer is operationally disabled and must be restarted by the operator.
Parameters
- ip-addr
Displays the BGP neighbor with the specified IP address.
- family family
Specifies the type of routing information to be distributed by the BGP instance.
- filter1
Specifies route criteria.
- filter2
Specifies route criteria.
