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 116 on page 604 lists the commands discussed in this section to configure LDP
signaling for VPLS.

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.

Configuring Routing in the Core Network for VPLS
After you configure the transparent bridging, LDP, and MPLS components of the VPLS
network, you must configure an IGP, such as OSPF or IS-IS, on the PE router to set up
routing within the core MPLS network.
This section explains one way to configure OSPF to enable routing in the core network.
Table 117 on page 605 lists the commands discussed in this section to configure OSPF.
