Configuring MPLS LSPs for VPLS

As part of a VPLS configuration, you must create MPLS label-switched paths (LSPs) to connect the local PE router and the remote PE router through the provider (P) router in the MPLS core. The requirements and procedures for subscriber policies are the same whether you employ BGP or LDP signaling for VPLS.

This section explains one way to create a basic MPLS configuration using the mpls and mpls ldp commands.

To configure MPLS LSPs on the PE router:

1. Enable MPLS on the default virtual router.

   host1(config)#mpls

2. Configure the core-facing interface on which you want to enable MPLS, Label Distribution Protocol (LDP), and topology-driven LSPs.

   host1(config)#interface atm 5/0.100

   host1(config-subif)#atm pvc 100 1 100 aal5snap 0 0 0

   host1(config-subif)#ip address 192.168.5.5 255.255.255.0

3. Create an MPLS major interface stacked on the layer 2 interface Enable MPLS on the core-facing interface.

   host1(config-subif)#mpls

4. Enable LDP and topology-driven LSPs on the core-facing interface, using the default values (that is, using an implicit default profile).

   host1(config-subif)#mpls ldp
