If no export or import keyword is specified, it means that the RT is both import and export. A VFI can have multiple

export or import RTs. However, the same RT is not allowed in multiple VFIs in the same PE.

Step 12 route-target import {as-number:nn | ip-address:nn}

Example:

RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd-vfi-ad)# route-target import 200:20

Specifies the import route target for the VFI.

Import route target is what the PE compares with the RT in the received NLRI: the RT in the received NLRI must

match the import RT to determine that the RTs belong to the same VPLS service.

Step 13 route-target export {as-number:nn | ip-address:nn}

Example:

RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd-vfi-ad)# route-target export 100:10

Specifies the export route target for the VFI.

Export route target is the RT that is going to be in the NLRI advertised to other PEs.

Step 14 signaling-protocol ldp

Example:

RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd-vfi-ad)# signaling-protocol ldp

Enables LDP signaling.

Step 15 vpls-id {as-number:nn | ip-address:nn}

Example:

RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd-vfi-ad-sig)# vpls-id 10:20

Specifies VPLS ID which identifies the VPLS domain during signaling.

This command is optional in all PEs that are in the same Autonomous System (share the same ASN) because a default

VPLS ID is automatically generated using BGP's ASN and the configured VPN ID (i.e., the default VPLS ID equals

ASN:VPN-ID). If an ASN of 4 bytes is used, the lower two bytes of the ASN are used to build the VPLS ID. In case

of InterAS, the VPLS ID must be explicitly configured. Only one VPLS ID can be configured per VFI, and the same

VPLS ID cannot be used for multiple VFIs.

Step 16 Use the commit or end command.

commit - Saves the configuration changes and remains within the configuration session.

end - Prompts user to take one of these actions:

• Yes - Saves configuration changes and exits the configuration session.

• No - Exits the configuration session without committing the configuration changes.
