Context

[Tree] (config>isa>aa-grp backup)

Full Context

configure isa application-assurance-group backup

Description

This command assigns an AA ISA or ESA-VM configured in the specified location to this application assurance group. The backup module provides the application assurance group with warm redundancy when the primary module in the group is configured. Primary and backup modules have equal operational status and when both module are coming up, the ones that becomes operational first becomes the active module. A module can serve as a backup for multiple AA ISA cards but only one can fail to it at one time.

On an activity switch from the primary module, configurations are already on the backup MDA but flow state information must be re-learned. Any statistics not yet spooled will be lost. Auto-switching from the backup to primary, once the primary becomes available again, is not supported.

Operator is notified through SNMP events when:

  • When the AA service goes down (all modules in the group are down) or comes back up (a module in the group becomes active).

  • When AA redundancy fails (one of the modules in the group is down) or recovers (the failed module comes back up).

  • When an AA activity switch occurred.

The no form of this command removes the specified module from the application assurance group.

Parameters

Context

[Tree] (config>isa>tunnel-grp backup)

Full Context

configure isa tunnel-group backup

Description

This command assigns a tunnel ISA configured in the specified slot to this IPsec group. The backup module provides the IPsec group with warm redundancy when the primary module in the group is configured. An IPsec group must always have a primary configured.

Primary and backup modules have equal operational status and when both modules are coming up, the one that becomes operational first becomes the active module. An IPsec module can serve as a backup for multiple IPsec groups but the backup can become active for only one ISA IPsec group at a time.

All configuration information is pushed down to the backup MDA from the CPM once the CPM gets notice that the primary module has gone down. This allows multiple IPsec groups to use the same backup module. Any statistics not yet spooled will be lost. Auto-switching from the backup to primary, once the primary becomes available again, is supported.

The operator is notified through SNMP events when:

  • When the ISA IPsec service goes down (all modules in the group are down) or comes back up (a module in the group becomes active).

  • When ISA IPsec redundancy fails (one of the modules in the group is down) or recovers (the failed module comes back up).

  • When an ISA IPsec activity switch took place.

The no form of this command removes the specified module from the IPsec group.

Default

no backup

Parameters

backup

Syntax

[no] backup ip-address

Context

[Tree] (config>router>if>vrrp backup)

Full Context

configure router interface vrrp backup

Description

This command associates router IP addresses with the parental IP interface IP addresses.

The backup command has two distinct functions when used in an owner or a non-owner context of the virtual router instance.

Non-owner virtual router instances actually create a routable IP interface address that is operationally dependent on the virtual router instance mode (master or backup). The backup command in owner virtual router instances does not create a routable IP interface address; it simply defines the existing parental IP interface IP addresses that are advertised by the virtual router instance.

For owner virtual router instances, the backup command defines the IP addresses that are advertised within VRRP advertisement messages. This communicates the IP addresses that the master is representing to backup virtual routers receiving the messages. Advertising a correct list is important. The specified ip-address must be equal to one of the existing parental IP interface IP addresses (primary or secondary) or the backup command fails.

For non-owner virtual router instances, the backup command actually creates an IP interface IP address used for routing IP packets and communicating with the system when the access commands are defined (ntp-reply, ping-reply, telnet-reply, and ssh-reply). The specified ip-address must be an IP address that is within one of the parental IP interface local subnets created with the address or secondary commands. If a local subnet does not exist that includes the specified ip-address or if ip-address is the same IP address as the parental IP interface IP address, the backup command fails.

The new interface IP address created with the backup command assumes the mask and parameters of the corresponding parent IP interface IP address. The ip-address is only active when the virtual router instance is operating in the master state. When not operating as master, the virtual router instance acts as if it is operationally down. It does not respond to ARP requests to ip-address, nor does it route packets received with its vrid derived source MAC address. A non-master virtual router instance always silently discards packets destined to ip-address. A single virtual router instance may only have a single virtual router IP address from a given parental local subnet. Multiple virtual router instances can define a virtual router IP address from the same local subnet as long as each is a different IP address.

In IPv4, up to sixteen backup ip-address commands can be executed within the same virtual router instance. Executing backup multiple times with the same ip-address results in no operation performed and no error generated. At least one successful backup ip-address command must be executed before the virtual router instance can enter the operational state.

When operating as (non-owner) master, the default functionality associated with ip-address is ARP response to ARP requests to ip-address, routing of packets destined to the virtual router instance source MAC address and silently discarding packets destined to ip-address. Enabling the non-owner-access parameters selectively allows ping, Telnet and SSH connectivity to ip-address when the virtual router instance is operating as master.

The no form of the command removes the specified virtual router IP address from the virtual router instance. For non-owner virtual router instances, this causes all routing and local access associated with the ip-address to cease. For owner virtual router instances, the no backup command only removes ip-address from the list of advertised IP addresses. If the last ip-address is removed from the virtual router instance, the virtual router instance will enter the operationally down state

Default

no backup — No virtual router IP address is assigned.

Parameters

ip-address

The virtual router IP address expressed in dotted decimal notation. The IP virtual router IP address must be in the same subnet of the parental IP interface IP address or equal to one of the primary or secondary IP addresses for owner virtual router instances.

Context

Full Context

configure router interface ipv6 vrrp backup

Description

This command associates router IPv6 addresses with the parental IP interface IP addresses.

The backup command has two distinct functions when used in an owner or a non-owner context of the virtual router instance.

Non-owner virtual router instances actually create a routable IP interface address that is operationally dependent on the virtual router instance mode (master or backup). The backup command in owner virtual router instances does not create a routable IP interface address; it simply defines the existing parental IP interface IP addresses that are advertised by the virtual router instance.

For owner virtual router instances, the backup command defines the IP addresses that are advertised within VRRP advertisement messages. This communicates the IP addresses that the master is representing to backup virtual routers receiving the messages. Advertising a correct list is important. The specified ipv6-addr must be equal to one of the existing parental IP interface IP addresses (link-local or global) or the backup command will fail.

For non-owner virtual router instances, the backup command actually creates an IP interface IP address used for routing IP packets and communicating with the system when the access commands are defined (ntp-reply, ping-reply, telnet-reply, and ssh-reply). The specified ipv6-addr must be an IP address that is within one of the parental IP interface local subnets created with the link-local-address or address commands. If a local subnet does not exist that includes the specified ipv6-addr or if ipv6-addr is the same IP address as the parental IP interface IP address, the backup command will fail.

The new interface IP address created with the backup command assumes the mask and parameters of the corresponding parent IP interface IP address. The ipv6-addr is only active when the virtual router instance is operating in the master state. For IPv6 VRRP, the parental interface's IP address that is in the same subnet as the backup address must be manually-configured, non EUI-64 and configured to be in the preferred state.

When not operating as master, the virtual router instance acts as if it is operationally down. It will not respond to Neighbor Solicitation (NS) requests to ipv6-addr, nor will it route packets received with its vrid derived source MAC address. A non-master virtual router instance always silently discards packets destined to ipv6-addr.

IPv6 allows the configuration of a link-local IPv6 address and multiple global IPv6 addresses on an interface. For each of these configured subnets, a virtual router IP address can be configured. Each IPv6 enabled device on a particular IPv6 subnet dynamically learns the connected IPv6 routers and correlated subnets in addition to the IPv6 default gateway using IPv6 neighbor discovery protocol (RFC4861). This protocol behavior is revised from IPv4 where the default gateway is manually configured or derived from supporting protocols (for example, DHCP). During the IPv6 neighbor discovery process, VRRP enabled routers will use backup IPv6 addresses and correlated derived virtual MAC addresses. Multiple virtual router instances can define a virtual router IP address from the same local subnet as long as each is a different IP address.

Executing backup multiple times with the same ipv6-addr results in no operation performed and no error generated. At least one successful backup ipv6-addr command must be executed before the virtual router instance can enter the operational state.

When operating as (non-owner) master, the default functionality associated with ipv6-addr results in the IPv6 Neighbor Advertisement response to IPv6 Neighbor Solicitation requests to ip-addr, routing of packets destined to the virtual router instance source MAC address, and silently discarding packets destined to ipv6-addr. An IPv6 virtual router instance can enter the operational state only if one of the configured backup addresses is a link-local address and the router advertisement of the interface is configured to use the virtual MAC address. Enabling the non-owner-access parameters selectively allows ping, Telnet, and traceroute connectivity to ipv6-addr when the virtual router instance is operating as master.

The no form of the command removes the specified virtual router IP address from the virtual router instance. For non-owner virtual router instances, this causes all routing and local access associated with the ipv6-addr to cease. For owner virtual router instances, the no backup command only removes ipv6-addr from the list of advertised IP addresses. If the last ipv6-addr or the link-local address is removed from the virtual router instance, the virtual router instance will enter the operationally down state

Default

no backup — No virtual router IP address is assigned.

Parameters

ipv6-address

The virtual router IP address is represented as eight groups of four hexadecimal digits, each group representing 16 bits (two octets). The groups are separated by colons (:). The IP virtual router IP address must be in the same subnet of the parental IP interface IP address or equal to one of the parent interface addresses for owner virtual router instances.

Full Context

configure router mpls lsp primary backup-class-type

Description

This command enables the use of the Diff-Serv backup Class-Type (CT), instead of the Diff-Serv main CT, to signal the LSP primary path when it fails and goes into retry. The Diff-Serv main CT is configured at the LSP level or at the primary path level using the following commands:

config>router>mpls>lsp>class-type ct-number

config>router>mpls>lsp>primary>class-type ct-number

When an LSP primary path retries due a failure, for example, it fails after being in the UP state, or undergoes any type of Make-Before-Break (MBB), MPLS will retry a new path for the LSP using the main CT. If the first attempt failed, the head-end node performs subsequent retries using the backup CT. This procedure must be followed regardless if the currently used CT by this path is the main or backup CT. This applies to both CSPF and non-CSPF LSPs.

The triggers for using the backup CT after the first retry attempt are:

  1. A local interface failure or a control plane failure (hello timeout and so on).

  2. Receipt of a PathErr message with a notification of a FRR protection becoming active downstream and/or Receipt of a Resv message with a 'Local-Protection-In-Use’ flag set. This invokes the FRR Global Revertive MBB.

  3. Receipt of a PathErr message with error code=25 ("Notify”) and sub-code=7 ("Local link maintenance required”) or a sub-code=8 ("Local node maintenance required”). This invokes the TE Graceful Shutdown MBB.

  4. Receipt of a Resv refresh message with the 'Preemption pending’ flag set or a PathErr message with error code=34 ("Reroute”) and a value=1 ("Reroute request soft preemption”). This invokes the soft preemption MBB.

  5. Receipt of a ResvTear message.

  6. A configuration change MBB.

  7. The user executing the clear>router>mpls>lsp command.

When an unmapped LSP primary path goes into retry, it uses the main CT until the number of retries reaches the value of the new main-ct-retry-limit parameter. If the path did not come up, it must start using the backup CT at that point in time. By default, this parameter is set to infinite value. The new main-ct-retry-limit parameter has no effect on an LSP primary path which retries due to a failure event.

An unmapped LSP primary path is a path which has never received a Resv in response to the first Path message sent. This can occur when performing a 'shut/no-shut’ on the LSP or LSP primary path or when the node reboots. An unmapped LSP primary path goes into retry if the retry timer expired or the head-end node received a PathErr message before the retry timer expired.

When the re-signal timer expires, CSPF will try to find a path with the main CT. The head-end node must re-signal the LSP even if the new path found by CSPF is identical to the existing one since the idea is to restore the main CT for the primary path. A path with main CT is not found, the LSP remains on its current primary path using the backup CT.

When the user performs a manual re-signal of the primary path, CSPF will try to find a path with the main CT. The head-end node must re-signal the LSP as in current implementation.

The no form of this command disables the use of the Diff-Serv backup CT.

Default

no backup-class-type

Parameters

ct-number

Specifies the Diff-Serv Class Type number. One or more system forwarding classes can be mapped to a CT.

configure router ospf segment-routing backup-node-sid

Description

This command enables LFA Protection using segment routing backup node SID.

The objective of this feature is to reduce the label stack pushed in a LFA tunnel next hop of inter-area and inter-domain prefixes. This is applicable in MPLS deployments across multiple IGP areas or domains such in seamless MPLS design.

The user enables the feature by configuring a backup node SID at an ABR/ASBR that is acting as a backup to the primary exit ABR/ASBR of inter-area or inter-as routes learned as BGP labeled routes. The user can enter either a label or an index for the backup node SID.

When a node in a IGP domain resolves a BGP label route for an inter-area or inter-domain prefix via the primary ABR exit router, it will use the backup node SID of this router, which is advertised by the backup ABR/ABR, as the LFA backup instead of the SID to the remote LFA PQ node to save on the pushed label stack.

This feature only allows the configuration of a single backup node SID per IGP instance and per ABR/ASBR. In other words, only a pair of ABR/ASBR nodes can back up each other in an IGP domain. Each time the user invokes the above command within the same IGP instance, it will override any previous configuration of the backup node SID. The same ABR/ASBR can, however, participate in multiple IGP instances and provide backup support within each instance.

Default

no backup-node-sid

Parameters

configure service vprn bgp backup-path

Description

This command enables the computation and use of a backup path for IPv4 and/or IPv6 BGP-learned prefixes belonging to the base router or a particular VPRN. Multiple paths must be received for a prefix to take advantage of this feature. When a prefix has a backup path and its primary paths fail, the affected traffic is rapidly diverted to the backup path without waiting for control plane reconvergence to occur. When many prefixes share the same primary paths, and in some cases also the same backup path, the time to failover traffic to the backup path is independent of the number of prefixes.

By default, IPv4 and IPv6 prefixes do not have a backup path installed in the IOM.

Default

no backup-path

Parameters

ipv4

Keyword that enables the use of a backup path for BGP-learned unlabeled IPv4 prefixes.

ipv6

Keyword that enables the use of a backup path for BGP-learned unlabeled IPv6 prefixes.

Description

This command specifies the bandwidth to be used for VLL bandwidth accounting by the VLL CAC feature.

The service manager keeps track of the available bandwidth for each SDP. The maximum value is the sum of the bandwidths of all constituent LSPs in the SDP. The SDP available bandwidth is adjusted by the user configured booking factor.

If an LSP consists of a primary and many secondary standby LSPs, then the bandwidth used in the maximum SDP available bandwidth is that of the active path. Any change to and LSP active path bandwidth will update the maximum SDP available bandwidth. Note however that a change to any constituent LSP bandwidth due to re-signaling of the primary LSP path or the activation of a secondary path which causes overbooking of the maximum SDP available bandwidth causes a warning and a trap to be issued but no further action is taken. The activation of a bypass or detour LSP in the path of the primary LSP does not change the maximum SDP available bandwidth.

When the user binds a VLL service to this SDP, an amount of bandwidth equal to bandwidth is subtracted from the SDP available bandwidth adjusted by the booking factor. When the user deletes this VLL service binding from this SDP, an amount of bandwidth equal to bandwidth is added back into the SDP available bandwidth.

If the total SDP available bandwidth when adding this VLL service is about to overbook, a warning is issued and the binding is rejected. This means that the spoke SDP bandwidth does not update the maximum SDP available bandwidth. In this case, the spoke SDP is put in operational down state and a status message of "pseudowire not forwarding” is sent to the remote SR-series PE node. A trap is also generated. The service manager will not put the spoke SDP into an operationally up state until the user executes a shutdown command and then a no-shutdown command of the spoke SDP and the bandwidth check succeeds. Therefore, the service manager will not automatically audit spoke SDPs subsequently to their creation to check if bandwidth is available.

If the VLL service contains an endpoint with multiple redundant spoke SDPs, each spoke SDP will have its bandwidth checked against the available bandwidth of the corresponding SDP.

If the VLL service performs a pseudowire switching (VC switching) function, each spoke SDP is separately checked for bandwidth against the corresponding SDP.

This feature does not alter the way service packets are sprayed over multiple RSVP LSPs, which are part of the same SDP. That is, by default load balancing of service packets occurs over the SDP LSPs based on service-id, or based on a hash of the packet header if ingress SAP shared queuing is enabled. In both cases, the VLL bandwidth is not checked against the available bandwidth of the selected LSPs but on the total SDP available bandwidth. Therefore, if there is a single LSP per SDP, these two matches.

If class-forwarding is enabled on the SDP, VLL service packets are forwarded to the SDP LSP which the packet forwarding class maps to, or if this is down to the default LSP. However, the VLL bandwidth is not checked against the selected LSP available bandwidth but on the total SDP available bandwidth. If there is a single LSP per SDP, these two matches.

If a non-zero bandwidth is specified for a VLL service and attempts to bind the service to an LDP or a GRE SDP, a warning is issued that CAC failed but the VLL is established. A trap is also generated.

The no form of this command reverts to the default value.

Description

This command specifies the bandwidth to be signaled for the path of the GMPLS LSP. Bandwidth is specified in terms of the RFC 3471 signal type name.

If an empty path is configured or the first hop TE Link is not configured, the system will automatically select a TE Link to use for a GMPLS LSP path based on the lowest available TE Link ID with a matching bandwidth (if a bandwidth is configured for the GMPLS LSP). During a data-bearer link allocation request, an RSVP-requested GMPLS LSP BW can be either a non-zero value as per RFC 3471 signal-type, or it can be zero). There are the following cases:

  • Case 1 — The requested BW is non-zero as per RFC 3471 Signal-type config:

    a) When a TE (or TE/DB) Link is configured in the related hop, LMP checks whether the related port BW is the same (exact match) as the requested BW, and allocates the port (provided any other checks are OK).

    b) When the related Hop is empty: LMP finds a db-link port to the peer node matching the requested BW, and allocates it.

  • Case 2 — Requested BW is zero:

    a) When a TE (or TE/DB) Link is configured in the related hop, LMP allocates the port (provided the other checks are OK), and provides the port BW to RSVP to use in signaling.

    b) When the related Hop is empty, LMP finds the first available db-link to the peer (based on lower db-link Id), and allocates it and provides the port BW to RSVP to use in signaling.

The no form of the command updates the bandwidth to zero.

Default

Description

This command assigns an existing bandwidth policer as an action on flows matching this AQP entry. The match criteria for the AQP entry must specify a uni-directional traffic direction before a policer action can be configured. If a policer is used in one direction in an AQP match entry the same policer name cannot be used by another AQP entry which uses a different traffic direction match criteria.

When multiple policers apply to a single flow, the final action on a packet is the worst case of all policer outcomes (for example, if one of the policers marks packet out of profile, the final marking will reflect that).

The no form of this command removes bandwidth policer from actions on flows matching this AQP entry.

Context

[Tree] (config>mcast-mgmt bandwidth-policy)

Full Context

configure mcast-management bandwidth-policy

Description

This command creates a multicast bandwidth policy. Bandwidth policies are used to manage the ingress multicast path bandwidth. Each forwarding plane supports multicast forwarding paths into the switch fabric. By default, two paths are available; the multicast high priority path and the multicast low priority path. Multicast packets are forwarded on either path based on the expedited or non-expedited (best-effort) nature of the queue the packets are scheduled from. The ingress forwarding plane uses the classification rules to determine the forwarding class of each multicast packet and uses the forwarding class to queue mapping to decide which ingress multipoint queue forwards the packet.

When multicast path management is enabled, the ingress forwarding plane allows IP multicast snooped or routed packets to be placed on to the two multicast paths independently of the ingress classification rules. The high priority multicast path is treated as the primary path and the low priority multicast path is treated as the secondary path. The ingress bandwidth manager evaluates each multicast FIB (M-FIB) record to determine which path is best based on ingress bandwidth, number of switch fabric destinations and the fill level of each path. Explicit path association is also supported.

Dynamic Bandwidth Activity Monitoring

When ingress multicast path management is enabled on an MDA, the system monitors the in-use bandwidth associated with each Layer 2 and Layer 3 ingress multicast record. When records are first populated by static, snooping or routing protocols, they are first assumed to be inactive. An inactive record is not considered to be currently consuming ingress multicast path bandwidth.

Within the multicast-info-policy, the bandwidth activity of the new record was configured to be either managed based on an administrative bandwidth, or based on the dynamic bandwidth rate table. The bandwidth-policy associated with ingress MDA contains the configuration parameters for creating the dynamic bandwidth rate table. The purpose of the table is to allow for the system to monitor the bandwidth activity associated with a multicast record and compare the current rate against several rate thresholds. Rate thresholds are used to allow a multicast streams rate to fluctuate between a given range while keeping the managed rate at a certain level. Multiple dynamic managed rates are supported in the table to allow monitoring of different types of multicast traffic. Each rate threshold is associated with a rising and falling threshold that defines when the specified rate should be used and when the next lower rate should be used.

Once a record’s monitored current rate rises to the first dynamic rising threshold, the record is active and the system then manages the bandwidth the record represents based on the parameters associated with the record in the records multicast-info-policy and the configured path information in the MDAs associated bandwidth-policy.

Ingress Multicast Path Parameters

The bandwidth-policy also contains the configuration parameters for each of the managed ingress multicast paths. The queue default parameters can be overridden for each primary and secondary path. In addition, the number of secondary paths (and by implication the number of primary paths) can be overridden.

Default Bandwidth Policy

A bandwidth policy with the name 'default’ always exists and is used as the default bandwidth policy when ingress multicast path management is enabled without an explicit bandwidth policy defined on an FP. The default policy cannot be deleted or edited.

The no form of this command removes the specified bandwidth policy from the system. The bandwidth policy associations must be removed from MDA configurations before it can be removed.

Default

bandwidth-policy "default”

Parameters

policy-name

Specifies the name of the bandwidth policy, up to 32 characters. Each bandwidth policy must be uniquely named within the system. 32 policies can be configured per system.

create

This keyword is required if creating a new bandwidth policy when the system is configured to require the explicit use of the keyword to prevent accidental object creation. Objects may be accidentally created when this protection is disabled and an object name is mistyped when attempting to edit the object. This keyword is not required when the protection is disabled. The keyword is ignored when the bandwidth policy name already exists.

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 or PIM) is notified of the fault.

The no form of this command removes BFD from the interface.

Note:

On the 7750 SR, the transmit-interval, receive receive-interval, and echo-receive echo-interval values can only be modified to a value less than 100 when:

  1. The type cpm-np option is explicitly configured.

  2. The service is shut down (shutdown)

  3. The interval is specified 10 to 100000.

  4. The service is re-enabled (no shutdown)

To remove the type cpm-np option, re-issue the bfd command without specifying the type parameter.

Description

This commands assigns a bi-directional forwarding (BFD) session providing heart-beat mechanism for the given VRRP/SRRP instance. There can be only one BFD session assigned to any given VRRP/SRRP instance, but there can be multiple SRRP/VRRP sessions using the same BFD session. If the interface configured with BFD is using a LAG or a spoke-SDP, the BFD transmit and receive intervals need to be set to a minimum of 300 ms.

BFD control the state of the associated interface. By enabling BFD on a given 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 via the BFD command under the IP interface. The specified interface may not be configured with BFD; when it is, the virtual router will then initiate the BFD session.

The no form of this command removes BFD from the configuration.

Parameters

service-id

Specifies the service ID of the interface running BFD. If no svc-id is specified then it indicates that the interface is a network interface in the Base router instance.

This variant of the command is only supported in 'classic' configuration-mode (configure system management-interface configuration-mode classic). The bfd-enable interface interface-name dst-ip ip-address name name variant can be used in all configuration modes.

Values

{id | svc-name}

id:

configure router ldp interface-parameters interface bfd-enable

Description

This command enables tracking of the Hello adjacency to an LDP peer using BFD.

The ipv6 option for this command is not supported on the 7450 ESS.

When this command is enabled on an LDP interface, LDP registers with BFD and starts tracking the LSR-id of all peers it formed Hello adjacencies with over that LDP interface. The LDP hello mechanism is used to determine the remote address to be used for the BFD session. The parameters used for the BFD session, that is, transmit-interval, receive-interval, and multiplier are those configured under the IP interface in existing implementation: config>router>if>bfd.

The operation of BFD over an LDP interface tracks the next-hop of the IPv4 and IPv6 prefixes in addition to tracking the LDP peer address of the Hello adjacency over that link. This is required since LDP can resolve both IPv4 and IPv6 prefix FECs over a single IPv4 or IPv6 LDP session and as such the next-hop of a prefix will not necessarily match the LDP peer source address of the Hello adjacency.

The failure of either or both of the BFD session tracking the FEC next-hop and the one tracking the Hello adjacency will cause the LFA backup NHLFE for the FEC to be activated or the FEC to be re-resolved if there is no FRR backup.

When multiple links exist to the same LDP peer, a Hello adjacency is established over each link and a separate BFD session is enabled on each LDP interface. If a BFD session times out on a specific link, LDP will immediately associate the LDP session with one of the remaining Hello adjacencies and trigger the LDP FRR procedures. As soon as the last Hello adjacency goes down due to BFD timing out, the LDP session goes down and the LDP FRR procedures will be triggered.

The no form of this command disables BFD on the LDP interface.

Description

The command associates the operational state of an MPLS-TP path with a BFD session whose control packets flow on the path. The BFD packets are encapsulated in a generic associated channel (G-ACh) on the path. The timer parameters of the BFD session are taken from the OAM template of the MEP.

A value of cc means that the BFD session is only used for continuity check of the MPLS-TP path. In this case, the CC timer parameters of the OAM template apply. A value of cv means that the BFD session is used for both continuity checking and connectivity verification, and the CV timers of the OAM template apply.

This form of the bfd-enable command is only applicable when it is configured under a MEP used on an MPLS-TP working or protection path.

Default

no bfd-enable

Parameters

cc

Indicates that BFD runs in CC only mode. This mode uses G-ACh channel type 0x07.

cc_cv

Indicates that BFD runs in combined CC and CV mode. This mode uses channel type 0x22 for MPLS-TP CC packets, and 0x23 for MPLS-TP CV packets.

configure router rsvp interface bfd-enable

Description

This command enables the use of bi-directional forwarding (BFD) to control the state of the associated RSVP interface. This causes RSVP to register the interface with the BFD session on that interface.

The user configures the BFD session parameters, such as, transmit-interval, receive-interval, and multiplier, under the IP interface in the config>router> if>bfd context.

Note:

It is possible that the BFD session on the interface was started because of a prior registration with another protocol, for example, OSPF or IS-IS.

The registration of an RSVP interface with BFD is performed at the time of neighbor gets its first session. This means when this node sends or receives a new Path message over the interface. If however the session did not come up, due to not receiving a Resv for a new path message sent after the maximum number of re-tries, the LSP is shutdown and the node de-registers with BFD. In general, the registration of RSVP with BFD is removed as soon as the last RSVP session is cleared.

The registration of an RSVP interface with BFD is performed independent of whether RSVP hello is enabled on the interface or not. However, hello timeout will clear all sessions towards the neighbor and RSVP de-registers with BFD at clearing of the last session.

An RSVP session is associated with a neighbor based on the interface address the path message is sent to. If multiple interfaces exist to the same node, each interface is treated as a separate RSVP neighbor. The user will have to enable BFD on each interface and RSVP will register with the BFD session running with each of those neighbors independently

Similarly the disabling of BFD on the interface results in removing registration of the interface with BFD.

When a BFD session transitions to DOWN state, the following actions are triggered. For RSVP signaled LSPs, this triggers activation of FRR bypass/detour backup (PLR role), global revertive (head-end role), and switchover to secondary if any (head-end role) for affected LSPs with FRR enabled. It triggers switchover to secondary if any and scheduling of re-tries for signaling the primary path of the non-FRR affected LSPs (head-end role).

The no form of this command removes BFD from the associated RSVP protocol adjacency.

Description

This commands assigns a bidirectional forwarding detect (BFD) session to a specific VRRP/SRRP instance. This BFD sessions provided a heartbeat mechanism that can be used to speed up the transition of the standby VRRP router to an active state. If the associated BFD session fails, the VRRP routers will immediately send a VRRP Advertisement message. In addition, the standby VRRP router(s) will transition to a Master state to speed convergence. The normal VRRP election process will then take place based on the Advertisement messages sent by all VRRP routers.

There can be only one BFD session assigned to any given VRRP/SRRP instance, but there can be multiple SRRP/VRRP sessions using the same BFD session.

The parameters used for the BFD sessions are set by the BFD command under the IP interface.

The no form of this command removes BFD from the configuration.

Parameters

interface-name

Specifies the name of the interface running BFD. The specified interface may not yet be configured with BFD. However, when it is, this virtual router will then initiate the BFD session.

Description

This command specifies the BIER-ID for this sub-domain. BIER-IDs should be assigned sequentially as the SI and BIER bit position are driven by the IDs. The equation used to drive BIER SI and bit positions from the ID is as follows:

SI = (BFR-id -1) /BitStringLength

bit position = ((BFR-id -1) modulo BitStringLength) +1

If the BIER-ID is sequential then the all bit positions in a bit string length will be utilized before moving on to the next SetID (SI).

BFR ID configuration is only necessary for BFIR and BFER, and not for transit BFRs

The no form of this command removes the BIER-ID.

Description

Commands in this context configure the BGP related parameters for BGP VPLS.

A maximum of two BGP instances can be configured in a VPLS service. The bgp-instance parameter value can be configured as 1 or 2. If it is not specified, the parameter value is configured as 1 by default.

The route-distinguisher configured in BGP instance 1 and 2 must be different. However, the route-target value may be configured the same or different for the two instances.

Only BGP-EVPN MPLS is allowed to be assigned to instance 2. Instance 1 must be used for the VXLAN and L2VPN address families.

BGP-EVPN VXLAN and BGP-EVPN MPLS can only be configured as no shutdown in the same service if they are associated with different instances (When the two BGP instances are created, the bgp-instance command must be configured in the bgp-evpn mpls context).

The evi value in bgp-evpn can be used to auto-derive the route distinguisher in instance 1 only. However, the evi value can be used to auto-derive the route-target in both instances.

Full Context

configure service system bgp-auto-rd-range

Description

This command defines the type-1 route-distinguisher IPv4 address and community value range within which the system will select a route-distinguisher for the bgp-enabled services using auto-rd.

Interactions:

This command is used along with the route-distinguisher auto-rd command supported in VPLS, VPRN and Epipe services. The system forces the user to create a bgp-auto-range before the auto-rd option can be used in the services.

The system will keep allocating values for services configured with route-distinguisher auto-rd as long as there are available community values within the configured range. After the command is added, the following changes are allowed:

  • The ip-address can be changed without modifying the comm-val range, even if services using auto-rd are present. The affected routes will be withdrawn and re-advertised with the new route-distinguishers.

  • The comm-val range can be modified as long as no conflicting values are present in the new range. For example, the user may expand the range as long as the new range does not overlap with existing manual route-distinguishers. The user may also reduce the range as long as the new range can accommodate the already allocated auto-RDs.

Parameters

ip-address

Specifies the IPv4 address used in the first 4 octets of all the type-1 auto route-distinguishers selected by the system.

comm-val

Specifies the community value of the type-1 auto route-distinguisher.

Description

This command causes qualifying matched BGP routes to be marked as leakable, meaning they are candidates to be leaked into other routing instances (copied with their complete set of path attributes). A BGP route is a qualifying route if it is an IPv4 route (unlabeled), IPv6 route (unlabeled) or a label-IPv4 route.

Note:

A leakable BGP route is not actually leaked into another routing instance unless it is accepted by a leak-import policy of that other routing instance.

The bgp-leak command has an effect only when the policy is applied as a BGP import policy in the base router or a VPRN context.

Full Context

configure router bgp bgp-tunnel-preference

Description

This command configures the tunnel table preference for BGP-LU tunnel type away from its default value.

The tunnel table preference applies to the next-hop resolution of BGP routes of the following families: EVPN, IPv4, IPv6, VPN-IPv4, VPN-IPv6, label-IPv4, and label-IPv6 in the tunnel table.

This feature does not apply to a VPRN, VPLS, or VLL service with explicit binding to an SDP which enabled the mixed-lsp-mode option. The tunnel preference, in such an SDP, is fixed and is controlled by the service manager. The configuration of the tunnel table preference parameter does not modify the behavior of such an SDP and the services that bind to it.

It is recommended to not set two or more tunnel types to the same preference value. In such a situation, the tunnel table prefers the tunnel type which was first introduced in SR OS implementation historically.

The no form of this command reverts to the default value.

Default

bgp-tunnel-preference 12

Parameters

preference

Specifies the BGP tunnel preference.

configure service vpls sap bgp-vpls-mh-ve-id

Description

This command upon the configuration of the ve-id under the SAP and if BGP-VPLS is configured and is operationally up, causes the PE to advertise a bgp-mh route for the ve-id (the route does not contain label information). The bgp-mh route contains the F and D flags properly set based on the SAP operational state. Upon switchover, the former active PE (DF in case of EVPN-MH) sends an update with a transition of the F bit from 1 to 0. This is an indication for the remote PEs to flush their MACs associated to the advertising PE.

This command is required when MC-LAG or EVPN-MH is used for multi-homing redundancy and mac-flush is required at remote BGP-VPLS PEs when there is a failure in the active PE.

The no form of this command withdraws the L2 VPN route.

Parameters

Description

The black-hole-dup-mac command is disabled by default. If enabled, a duplicated MAC detected in the network is programmed as a black-hole MAC in the FDB and displayed in the show service id fdb detail command as follows:

  • Source-Identifier—black-hole

  • Type—EvpnD:P

Because the MAC is now programmed in the FDB as a black-hole, all received frames with MAC DA matching the duplicate MAC are discarded. The duplicate black-hole MACs are installed as Protected, therefore, all received frames with MAC SA matching the duplicate MAC are discarded by default.

A BGP-EVPN (MPLS or VXLAN) shutdown is required to add or remove the black-hole-dup-mac command.

The no form of the command removes the feature, and duplicate MACs are no longer programmed as black-hole MACs.

Description

This command creates or edits the boot option file (BOF) for the specified local storage device.

A BOF file specifies where the system searches for runtime images, configuration files, and other operational parameters during system initialization.

BOF parameters can be modified. Changes can be saved to a specified compact flash. The BOF must be located in the root directory of either an internal or external compact flash local to the system and have the mandatory filename of bof.cfg.

When modifications are made to in-memory parameters that are currently in use or operating, the changes are effective immediately. For example, if the IP address of the management port is changed, the change takes place immediately.

Only one entry of the BOF configuration command statement can be saved once the statement has been found to be syntactically correct.

When opening an existing BOF that is not the BOF used in the most recent boot, a message is issued notifying the user that the parameters will not affect the operation of the node.

No default boot option file exists. The router boots with the factory default boot sequence and options.

Description

This command specifies the booking factor applied against the port or LAG administrator bandwidth by SAP administrator bandwidth CAC.

The service manager keeps track of the available administrator bandwidth for each port or LAG configured with an administrator bandwidth. The port or LAG available administrator bandwidth is adjusted by the user configured booking factor, allowing the port or LAG bandwidth to be overbooked or under booked.

If the booking factor is increased then available administrator bandwidth on the port or LAG increases. If the booking factor is decreased then available administrator bandwidth on the port or LAG decreases. However, if the reduction of available administrator bandwidth is insufficient to cover the sum of the current SAP administrator bandwidth on the port or LAG, the command fails.

The no form of this command reverts to the default value.

configure redundancy bgp-evpn-multi-homing boot-timer

Description

This command allows the necessary time for the control plane protocols to come up upon PE boot-up before bringing up the ESs and running the DF algorithm.

The following considerations apply to this command:

  • The boot-timer command must provide enough time to allow the IOMs and BGP sessions to come up before exchanging ES routes and running the DF election for each EVI or ISID.

  • The boot-timer is synchronized across CPMs and is relative to the system up time; it is not changed or reset upon CPM switchover.

  • The boot-timer is never interrupted (the es-activation-timer, however, can be interrupted if there is a new event triggering the DF election).

  • The boot-timer runs per EVI or ISID on the ESs in the system. If the system up time (time the system has been up since the last reboot) is less than the boot-timer value, the system does not run the DF election for any EVI or ISID. When the boot-timer value expires, the DF election runs, and if the system is elected DF for the EVI or ISID, the es-activation-timer is triggered.

  • The system does not advertise ES routes until the boot timer expires, which guarantees that the peer ES PEs only run the DF election when the PE is ready to become the DF, if required.
