5.
Configure a loopback interface to be associated with the targeted LDP neighbor,
and assign a router ID that uses the IP address of the loopback interface.
For instructions, see “Configuring the Loopback Interface and Router ID for VPLS”
on page 598.
6.
Configure MPLS LSPs to connect local and remote PE routers.
For instructions, see “Configuring MPLS LSPs for VPLS” on page 599.
7.
Set up LDP signaling for this VPLS instance to establish targeted sessions to the
remote PE neighbors configured at the edge of the MPLS core network.
8.
Configure an interior gateway protocol (IGP), such as Open Shortest Path First
(OSPF) or Intermediate System–to–Intermediate System (IS-IS), to enable routing
within the core network.

Configuring VPLS Instances with LDP Signaling
As is the case with BGP signaling, when you use LDP signaling you must configure
a VPLS instance for each VPLS domain in which the router participates. Unlike BGP
signaling, however, configuring a VPLS instance for LDP signaling requires only that
you specify the transport virtual router for this instance by issuing the
bridge vpls
transport-virtual-router command.
To configure a basic VPLS instance with LDP signaling on the PE router:
■
From Global Configuration mode, create the VPLS instance by specifying the
transport virtual router for this instance.
host1(config)# bridge customer3 vpls transport-virtual-router vr1
The transport virtual router specifies the name of the virtual router on which the
LDP instance that signals reachability for this VPLS instance is configured. If the
bridge group you specify (customer3 in this example) already exists on the router,
issuing this command causes the bridge group to become a VPLS instance.
