PBB Service Commands
VPLS Service Commands
vpls
Syntax 
vpls service-id customer customer-id vpn vpn-id [m-vpls] [b-vpls | i-vpls] [create]
vpls service-id
no vpls service-id
Context 
config>service
Description 
This command creates or edits a Virtual Private LAN Services (VPLS) instance. The vpls command is used to create or maintain a VPLS service. 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.
A VPLS service connects multiple customer sites together acting like a zero-hop, layer 2 switched domain. A VPLS is always a logical full mesh.
When a service is created, the create keyword must be specified if the create command is enabled in the environment context. When a service is created, the customer keyword and customer-id must be specified and associates the service with a customer. The customer-id must already exist having been created using the customer command in the service context. Once a service has been 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.
Once a service is created, the use of the customer customer-id is optional for navigating into the service configuration context. Attempting to edit a service with the incorrect customer-id specified will result in an error.
More than one VPLS service may be created for a single customer ID.
By default, no VPLS instances exist until they are explicitly created.
The no form of this command deletes the VPLS service instance with the specified service-id. The service cannot be deleted until all SAPs and SDPs defined within the service ID have been shutdown and deleted, and the service has been shutdown.
service-id
The unique service identification 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 SR OS router on which this service is defined.
Values
1 — 2147483648
vpls custome
customer
customer customer-id
Specifies the customer ID number to be associated with the service. This parameter is required on service creation and optional for service editing or deleting.
Values
1 — 2147483647
vpls vpn
vpn vpn-id
Specifies the VPN ID number which allows you to identify virtual private networks (VPNs) by a VPN identification number.
Values
1 — 2147483647
Default
null (0)
m-vpls
Specifies a management VPLS.
b-vpls | i-vpls
Creates a backbone-vpls or ISID-vpls for use with PBB
service-name
Syntax 
service-name service-name
no service-name
Context 
config>service>vpls
Description 
This command configures an optional service name, up to 64 characters in length, which adds a name identifier to a given service to then use that service name in configuration references as well as display and use service names in show commands throughout the system. This helps the service provider/administrator to identify and manage services within the 7750 SR, 7450 ESS and 7710 SR platforms.
All services are required to assign a service ID to initially create a service. However, either the service ID or the service name can be used o identify and reference a given service once it is initially created.
Parameters 
service-name
Specifies a unique service name to identify the service. Service names may not begin with an integer (0-9).
eth-tunnel
Syntax 
eth-tunnel tunnel-id
Context 
config>service>vpls
Description 
This command associates a BVPLS SAP with the global Ethernet tunnel object specified by tunnel-id. Only one-to-one mapping between SAP and Ethernet tunnel is supported in the initial implementation. The global eth-tunnel tunnel-id with at least a member port must be configured in advance for the command to be successful. A SAP will be instantiated using the active path components (member port and control-tag) for VPLS forwarding. The last member port in the Ethernet Tunnel cannot be deleted if there is a SAP configured on that eth-tunnel. This command is only available in the BVPLS context.
The no form of this command removes the sap from the Ethernet tunnel object.
Default 
no sap is specified
Parameters 
tunnel-id
Specifies the value of the Ethernet tunnel identifier to be used for the SAP.
Values
1-64
spb
Syntax 
[no] spb instance [fid value] [create]
Context 
config>service>vpls <instance> b-vpls
config>service>vpls <instance> b-vpls>sap>spb
config>service>vpls <instance> b-vpls>spoke-sdp>spb
Description 
This command enables Shortest Path Bridging (SPB) on a B-VPLS instance. SPB uses IS-IS that supports multiple instances, therefore an instance must be specified. The declaration of SPB in this context is the control configuration for the SPB. This is an SPB management interface and it manages the configuration for IS-IS. Various parameters that define this SPB instance are configured under this SPB instance. Several of the parameters are shared with other B-VPLS service instances using SPB.
SPB enables an instance of IS-IS protocol with the no shutdown command. Alternatively, the IS-IS protocol instance under SPB is disabled with the shutdown command in the config>service>vpls <instance> b-vpls>spb context.
A Forwarding Identifier (FID) is optionally specified which is an abstraction of the B-VID used for forwarding in SPB. When no FID is configured the control VPLS is advertised with FID value 1. When a FID value is specified, the control VPLS is advertised and associated with the FID value specified. The default algorithm for any FID declared or implicit is low-path-id. When a FID is specified, the ect-algorithm can be specified for the FID and changed only when there are no VPLS, SAPs or SDP bindings associated with the FID. The FID for a control instance cannot be changed once created. To change a FID the SPB component would have to be shutdown, deleted and recreated with a new FID.
Default 
no spb
Parameters 
instance-id
Specifies the instance ID for an SPB IS-IS instance.
Values
1024–2047 (4 available)
Default
1024
FID
Specifies FID value.
Values
1-4095
Default
1
Note: SPB operates with disable-learning, disable aging and discard-unknown. The state of these commands is ignored when SPB is configured.
spb
Syntax 
[no] spb [create]
Context 
config>service>vpls <instance> b-vpls>sap>spb>
config>service>vpls <instance> b-vpls>spoke-sdp>spb>
Description 
This command enables Shortest Path Bridging (SPB) on SAP or Spoke SDP. The B-VPLS may be a control B-VPLS or user B-VPLS. Since SPB uses IS-IS that supports multiple instances, SPB inherits the instance from the control B-VPLS.
SPB at this context level is enabled immediately. SPB enables an instance of IS-IS protocol with the no shutdown command. Alternatively, the IS-IS protocol instance under SPB is disabled with the shutdown command in the config>service>vpls <instance> b-vpls>spb context.
Default 
no spb
spbm-control-vpls
Syntax 
spbm-control-vpls service-id fid fid
no spbm-control-vpls
Context 
config>service>vpls service-id b-vpls>
Description 
This command associates a user B-VPLS with a particular control B-VPLS and a FID. The ECT algorithm and the behavior of unicast and multicast come from the association to the FID.
A Forwarding Identifier (FID) is specified which is an abstraction of the B-VID used for forwarding in SPB. The ect-algorithm is associated with the FID and can be changed only when there are no VPLS, SAPs or SDP bindings associated with the FID. The FID must be independent from the FID assigned to other services.
 
none
shutdown
Syntax 
[no] shutdown
Context 
config>service>vpls <instance> b-vpls>spb>
config>service>vpls <instance> b-vpls>sap>spb>
config>service>vpls <instance> b-vpls>spoke-sdp>spb>
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.
The no form of this command administratively enables an entity.
SPB Interface — In the config>service>vpls <instance> b-vpls>spb> context, the command disables the IS-IS interface. By default, the IS-IS interface is disabled, shutdown.
lsp-lifetime
Syntax 
lsp-lifetime seconds
no lsp-lifetime
Context 
config>service>vpls <instance> b-vpls>spb
Description 
This command sets the time, in seconds, SPB wants the LSPs it originates to be considered valid by other routers in the domain. This is a control B-VPLS command.
Each LSP received is maintained in an LSP database until the lsp-lifetime expires unless the originating router refreshes the LSP. By default, each router refreshes its LSP’s every 20 minutes (1200 seconds) so other routers will not age out the LSP.
The LSP refresh timer is derived from this formula: lsp-lifetime/2
The no form of the command reverts to the default value.
Default 
1200 — LSPs originated by SPB should be valid for 1200 seconds (20 minutes).
Parameters 
seconds
The time, in seconds, that SPB wants the LSPs it originates to be considered valid by other routers in the domain.
Values
350 — 65535
lsp-wait
Syntax 
lsp-wait lsp-wait [lsp-initial-wait [lsp-second-wait]]
Context 
config>service>vpls <instance> b-vpls>spb
Description 
This command is used to customize the throttling of SPB LSP-generation. Timers that determine when to generate the first, second and subsequent LSPs can be controlled with this command. Subsequent LSPs are generated at increasing intervals of the second lsp-wait timer until a maximum value is reached. This is a control B-VPLS command.
Parameters 
lsp-max-wait
Specifies the maximum interval in seconds between two consecutive occurrences of an LSP being generated.
Values
1 — 120
Default
5
lsp-initial-wait
Specifies the initial LSP generation delay in seconds.
Values
0 — 100
Default
0
lsp-second-wait
Specifies the hold time in seconds between the first and second LSP generation.
Values
1 — 100
Default
1
overload
Syntax 
overload [timeout seconds]
no overload
Context 
config>service>vpls <instance> b-vpls>spb
Description 
This command administratively sets the SPB to operate in the overload state for a specific time period, in seconds, or indefinitely. During normal operation, the router may be forced to enter an overload state due to a lack of resources. When in the overload state, the router is only used if the destination is reachable by SPB and will not used for other transit traffic.
If a time period is specified, the overload state persists for the configured length of time. If no time is specified, the overload state operation is maintained indefinitely.
The overload command can be useful in circumstances where SPB is overloaded or used prior to executing a shutdown command to divert traffic around the switch.
The no form of the command causes the router to exit the overload state.
Default 
no overload
Parameters 
seconds
The time, in seconds, that this router must operate in overload state.
Values
60 — 1800
Default
Infinity (overload state maintained indefinitely)
overload-on-boot
Syntax 
overload-on-boot [timeout seconds]
no overload-on-boot
Context 
config>service>vpls <instance> b-vpls>spb>
Description 
When the router is in an overload state, SPB the B-VPLS is used only if there is no other SPB B-VPLS 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 config>service>vpls instance>b-vpls>spb>no overload command.
The no form of the command does not affect the overload-on-boot function.
If no timeout is specified, SPB IS-IS goes into overload indefinitely after a reboot. After the reboot, the SPB IS-IS status displays a permanent overload state:
L1 LSDB Overload : Manual on boot (Indefinitely in overload)
This state can be cleared with the config>service>vpls instance >b-vpls>spb>no overload command.
When specifying a timeout value, SPB IS-IS goes into overload for the configured timeout after a reboot. After the reboot, SPB IS-IS status displays the remaining time the system stays in overload:
L1 LSDB Overload : Manual on boot (Overload Time Left : 17)
The overload state can be cleared before the timeout expires with config>service>vpls instance>b-vpls>spb>no overload command.
The no form of the command removes the overload-on-boot functionality from the configuration.
Default 
no overload-on-boot
Parameters 
seconds
The time, in seconds, that this router must operate in overload state.
Values
60 — 1800
Default
Infinity (overload state maintained indefinitely)
spf-wait
Syntax 
[no] spf-wait spf-wait [spf-initial-wait [spf-second-wait]]
Context 
config>service>vpls <instance> b-vpls>spb>
Description 
This command defines the maximum interval between two consecutive SPF calculations in seconds. 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, then the next SPF will run after 2000 milliseconds, and then next SPF will run after 4000 milliseconds, etc., until it reaches the spf-wait value. The SPF interval remains 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.
Default 
no spf-wait
Parameters 
spf-wait
Specifies the maximum interval in seconds between two consecutive spf calculations.
Values
1 — 120
Default
10
spf-initial-wait
Specifies the initial SPF calculation delay in milliseconds after a topology change.
Values
10 — 100000
Default
1000
spf-second-wait
Specifies the hold time in milliseconds between the first and second SPF calculation.
Values
1 — 100000
Default
1000
level
Syntax 
level level-number
Context 
config>service>vpls <instance> b-vpls>spb
Description 
This command creates the context to configure SPB Level 1 or Level 2 area attributes. This is IS-IS levels. Only Level 1 can be configured.
A Level 1 adjacency can be established only with other Level 1 B-VPLS. A Level 2 adjacency can be established only with other Level 2 B-VPLS. Currently there is no support for level 1 and level 2 in the same instance of SPB.
Default 
level 1
Parameters 
level-number
The SPB level number.
Values
1, 2
bridge-priority
Syntax 
bridge-priority value
Context 
config>service>vpls <instance> b-vpls>spb>level level-number
Description 
This command configures the four bit bridge priority for Shortest Path Bridging. This value is added to the 6 byte bridge Identifier (which is the system-id) in the top four bits of a two byte field. Note the actual value will be bit shifted 12 bits left effective putting this in the high bits of the 16 bits added to system ID.
The bridge priority is important in choosing the Root Bridge for the single tree algorithm (lowest value = best). Bridge priority also factors into the tie breaker for SPF algorithms as described in the SPB standard. The bridge-identifier (system-id) of the control B-VPLS determines the tiebreaker when the bridge-priorities are equal.
Values
0 — 15
Default 
8
ect-algorithm
Syntax 
ect-algorithm name fid-range fid-range
Context 
config>service>vpls <instance> b-vpls>spb>level level-number
Description 
This command configures the ect-algorithm associated with a FID. Names are:
•
low-path-id
•
high-path-id
The algorithm for low-path-id chooses the path with the lowest metric and uses the sum of each Bridge-ID to break-ties (in this case preferring the lowest bridge identifiers).
The algorithm for high-path-id choose the path with the lowest metric and the sum of each Bridge-ID (after each one is modified by the algorithm mask) to break-ties (in this case preferring the highest bridge identifiers).
A Forwarding Identifier (FID) is an abstraction of the IEEE 802.1 SPB Base VID and represents the VLAN (B-VPLS) in IS-IS LSPs. B-VPLS services with the same FID share B-MACs and I-SIDs. (the SAP encapsulation VLAN tag may be set to the same value as the FID or to any other valid VLAN tag). One or more FIDs can be associated with an ECT-algorithm by using the FID range. User B-VPLS services may share the same FID as the control B-VPLS or use independent FIDs where each FID has an assigned ect-algorithm. B-VPLS services with i-vpls services must have an independent FID. B-VPLS services with only PBB Epipes may share FIDs with other B-VPLS services including the control B-VPLS service.
The ect-algorithm is associated with the FID and can only be changed only when there are no VPLS, SAPs or SDP bindings associated with the FID. The FID must be independent from the FID assigned to other services.
Default 
low-path-id
Parameters 
name
low-path-id, high-path-id
fid-range
Range of Forwarding Identifier values.
Values
1 — 4095

leave-time
Syntax 
[no] leave-time value
Context 
config>service>vpls>sap>mrp
config>service>vpls>spoke-sdp>mrp
config>service>vpls>mesh-sdp>mrp
Description 
This command controls the period of time that the Registrar state machine will wait in the leave state before transitioning to the MT state when it is removed. An instance of the timer is required for each state machine that is in the leave state. The Leave Period Timer is set to the value leave-time when it is started.
A registration is normally in “in” state where there is an MFIB entry and traffic is being forwarded. When a “leave all” is performed (periodically around every 10-15 seconds per SAP/SDP binding - see leave-all-time-below), a node sends a message to its peer indicating a leave all is occurring and puts all of its registrations in leave state.
The peer refreshes its registrations based on the leave all PDU it receives and sends a PDU back to the originating node with the state of all its declarations.
Refer to IEEE 802.1ak-2007 section 10.7.4.2.
Default 
30

send-flush-on-failure
Syntax 
[no] send-flush-on-failure
Context 
config>service>vpls
Description 
This command enables sending out “flush-all-from-ME” messages to all LDP peers included in affected VPLS, in the event of physical port failures or “oper-down” events of individual SAPs. This feature provides an LDP-based mechanism for recovering a physical link failure in a dual-homed connection to a VPLS service. This method provides an alternative to RSTP solutions where dual homing redundancy and recovery, in the case of link failure, is resolved by RSTP running between a PE router and CE devices. If the endpoint is configured within the VPLS and send-flush-on-failure is enabled, flush-all-from-me messages will be sent out only when all spoke SDPs associated with the endpoint go down.
This feature cannot be enabled on management VPLS.
Default 
no send-flush-on-failure

force-qtag-forwarding
Syntax 
[no] force-qtag-forwarding
Context 
config>service>vpls ivpls>pbb
Description 
This command forces the addition of a IEEE 802.1q tag after the Customer MAC (CMAC) address when the PBB header is built as it egresses a related BVPLS. It is used to preserve the dot1q and DE bits from the customer domain when the service delimiting qtags are stripped as the packet is ingressing a PBB Epipe or an IVPLS. The VLAN value of the service delimiting QTAG, if one exists, is used for the corresponding inserted dot1q field. If a service delimiting QTAG does not exist, then the value of zero is used for all the inserted QTAG bits. The no form of this command sets default behavior.
The no form of this command disables the command.
source-bmac
Syntax 
source-bmac ieee-address
Context 
config>service>vpls bvpls>pbb
Description 
This command configures the base source BMAC for the B-VPLS. The first 32 bits must be the same with what is configured in the MC-LAG peer. If not configured here, it will inherit the chassis level BMAC configured under the new PBB object added in the previous section. If the use-sap-bmac command is on, the value of the last 16 bits (lsb) of the source BMAC must be part of the reserved-source-bmac-lsb configured at chassis level, under service PBB component. If that is not the case, the command will fail.
use-sap-bmac
Syntax 
[no] use-sap-bmac
Context 
config>service>vpls bvpls>pbb
Description 
This command enables on a per BVPLS basis the use of source BMACs allocated to multi-homed SAPs (assigned to an MC-LAG) in the related IVPLS or Epipe service. The command will fail if the value of the source-bmac assigned to the BVPLS is the hardware (chassis) BMAC. In other words, the source-bmac must be a configured one.
Default 
no use-sap-bmac
mac-notification
Syntax 
mac-notification
Context 
config>service>vpls bvpls
Description 
This command controls the settings for the MAC notification message.
The mac-notification message must be generated under the following events:
1.
When enabled in the BVPLS using no shutdown, a MAC notification will be sent for every active MC-LAG link. The following 3 cases assume no shutdown in the BVPLS.
2.
Whenever a related MC-LAG link becomes active (related MC-LAG link = has at least 1 SAP associated with the BVPLS) if the MC-LAG peering is initialized and the PE peers are synchronized.
3.
1st SAP on an active MC-LAG is associated (via IVPLS/Epipe) with the BVPLS
4.
The link between IVPLS/Epipe and BVPLS is configured and there are I-SAPs configured on an active MC-LAG link.
The MAC notification is not sent for the following events:
1.
Change of source-bmac or source-bmac-lsb
2.
On changes of use-sap-bmac parameter
3.
If MC-LAG peering is not (initialized and in sync).

mrouter-port
Syntax 
[no] mrouter-port
Context 
config>service>vpls>pbb>backbone-vpls>sap>igmp-snooping
config>service>vpls>pbb>backbone-vpls>sdp>igmp-snooping
Description 
This command specifies whether a multicast router is attached behind this SAP.
Configuring a SAP as an mrouter-port will have a double effect. Firstly, all multicast traffic received on another SAP will be copied to this SAP. Secondly, IGMP reports generated by the system as a result of someone joining or leaving a multicast group, will be sent to this SAP or SDP.
If two multicast routers exist in the network, one of them will become the active querier. While the other multicast router (non-querier) stops sending IGMP queries, it should still receive reports to keep its multicast trees up to date. To support this, the mrouter-port should be enabled on all SAPs connecting to a multicast router.
Note that the IGMP version to be used for the reports (v1, v2 or v3) can only be determined after an initial query has been received. Until such time no reports are sent on the SAP, even if mrouter-port is enabled.
If the send-queries command is enabled on this SAP, the mrouter-port parameter can not be set.
Default 
no mrouter-port

force-qtag-forwarding
Syntax 
[no] force-qtag-forwarding
Context 
config>service>vpls ivpls>pbb
config>service>epipe>pbb
Description 
This command forces the addition of a IEEE 802.1q tag after the Customer MAC (CMAC) addresses when the PBB header is built, as it egresses a related BVPLS.
It is used to preserve the dot1q and DE bits from the customer domain when the service delimiting qtags are stripped when the packet is ingressing a PBB Epipe or an IVPLS. The VLAN value of the service delimiting QTAG if one exists is used for the corresponding inserted dot1q field. If a service delimiting QTAG does not exist, then the value of zero is used for all the inserted QTAG bits.
The no form of this command sets default behavior.
Default 
disabled
mrp-policy
Syntax 
[no] mrp-policy
Context 
config>service>vpls>sap>mrp
config>service>vpls>spoke-sdp>mrp
config>service>vpls>mesh-sdp>mrp
Description 
This command instructs MMRP to use the mrp-policy defined in the command to control which group BMAC attributes will be declares and registered on the egress SAP/Mesh-SDP/Spoke-SDP. The Group BMACs will be derived from the ISIDs using the procedure used in the PBB solution. The Group MAC = standard OUI with the last 24 bits being the ISID value. If the policy-name refers to a non-existing mrp-policy the command should return error. Changes to a mrp-policy are allowed and applied to the SAP/SDPs under which the policy is referenced.
Default 
no mrp-policy

epipe
Syntax 
epipe service-id customer customer-id [vpn vpn-id] [vc-switching] [create]
epipe service-id
no epipe service-id
Context 
config>service
Description 
This command configures an Epipe service instance. This command is used to configure a point-to-point epipe service. An Epipe connects two endpoints defined as Service Access Points (SAPs). Both SAPs may be defined in one 7750 SR or they may be defined in separate 7750 SR devices connected over the service provider network. When the endpoint SAPs are separated by the service provider network, the far end SAP is generalized into a Service Distribution Point (SDP). This SDP describes a destination 7750 SR and the encapsulation method used to reach it.
No MAC learning or filtering is provided on an Epipe.
When a service is created, the customer keyword and customer-id must be specified and associates the service with a customer. The customer-id must already exist having been created using the customer command in the service context. Once a service has been 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.
Once a service is created, the use of the customer customer-id is optional for navigating into the service configuration context. Attempting to edit a service with the incorrect customer-id specified will result in an error.
By default, no epipe services exist until they are explicitly created with this command.
The no form of this command deletes the epipe service instance with the specified service-id. The service cannot be deleted until the service has been shutdown.
service-id-epipe
service-id
The unique service identification 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 7750 SR on which this service is defined.
Values
1 — 2147483648
epipe customer
customer customer-id
Specifies the customer ID number to be associated with the service. This parameter is required on service creation and optional for service editing or deleting.
Values
1 — 2147483647
vpn
vpn vpn-id
Specifies the VPN ID number which allows you to identify virtual private networks (VPNs) by a VPN ID. If this parameter is not specified, the VPN ID uses the same service ID number.
Values
1 — 2147483647
Default
null (0)
vc-switching
Specifies if the pseudowire switching signalling is used for the spoke SDPs configured in this service.
create
Keyword used to create the service instance. The create keyword requirement can be enabled/disabled in the environment>create context.
