# 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.
