Implementing Multipoint Layer 2 Services
Example:
RP/0/RP0/CPU0:router(config-l2vpn)# bridge group metroA
Enters configuration mode for the named bridge group.
Step 5 bridge-domain bridge-domain-name
Example:
RP/0/RP0/CPU0:router(config-l2vpn-bg)# bridge-domain east
Enters configuration mode for the named bridge domain.
Step 6
vfi {vfi-name}
Example:
RP/0/RP0/CPU0:router(config-l2vpn-bg-bd)# vfi vfi-east
Enters virtual forwarding instance (VFI) configuration mode.
Step 7 autodiscovery bgp
Example:
RP/0/RP0/CPU0:router(config-l2vpn-bg-bd-vfi)# autodiscovery bgp
Enters BGP autodiscovery configuration mode where all BGP autodiscovery parameters are configured.
This command is not provisioned to BGP until at least the VPN ID and the signaling protocol is configured.
Step 8 vpn-id vpn-id
Example:
RP/0/RP0/CPU0:router(config-l2vpn-bg-bd-vfi)# vpn-id 100
Specifies the identifier for the VPLS service. The VPN ID has to be globally unique within a PE router. i.e., the same
VPN ID cannot exist in multiple VFIs on the same PE router. In addition, a VFI can have only one VPN ID.
Step 9 rd {as-number:nn | ip-address:nn | auto}
Example:
RP/0/RP0/CPU0:router(config-l2vpn-bg-bd-vfi-ad)# rd auto
Specifies the route distinguisher (RD) under the VFI.
The RD is used in the BGP NLRI to identify VFI. Only one RD can be configured per VFI, and except for rd auto the
same RD cannot be configured in multiple VFIs on the same PE.
When rd autois configured, the RD value is as follows: {BGP Router ID}:{16 bits auto-generated unique index}.
Step 10 route-target {as-number:nn | ip-address:nn | export | import }
