# Configuring LDP Signaling for VPLS

LDP signaling establishes targeted sessions to the remote VEs configured at the edge of the service provider’s MPLS core network. To enable LDP to establish these targeted sessions, you issue the mpls ldp vpls-id command to configure a VPLS identifier for the VPLS instance, and the mpls ldp vpls neighbor command to configure a list of neighbor (peer) addresses to which LDP can send or from which LDP can receive targeted hello messages.

This section describes how to configure LDP signaling for a VPLS network, but does not provide complete details about configuring LDP on E-series routers.

Table 81 lists the commands discussed in this section to configure LDP signaling for VPLS.

Table 81: Commands to Configure LDP Signaling for VPLS

mpls ldp vpls neighbor | mpls ldp vpls vpls-id

To configure LDP signaling for VPLS on the PE router:

1. Configure the VPLS identifier, which is a globally unique identifier for each VPLS domain.
   `
   host1(config)#mpls ldp vpls customer3 vpls-id 3
   `
2. Enable LDP signaling for a VPLS instance by configuring a list of neighbor (peer) addresses on remote VE devices in the VPLS domain to which LDP can send or from which LDP can receive targeted hello messages.
   `
   host1(config)#mpls ldp vpls customer3 neighbor 10.3.3.3
   host1(config)#mpls ldp vpls customer3 neighbor 10.3.10.100
   `
3. Repeat these steps for each VPLs instance on the PE router.
