# Configuration Tasks for VPLS with LDP Signaling

To configure VPLS with LDP signaling on the PE router:

1. Configure a single instance of VPLS, known as a VPLS instance, on the PE router for each VPLS domain in which the router participates.
2. (Optional) Configure optional attributes for the VPLS instance.

   For instructions, see Configuring Optional Attributes for VPLS Instances.

3. Configure network interfaces to connect the PE router to each CE device.

   For instructions, see Configuring VPLS Network Interfaces.

4. (Optional) Configure nondefault subscriber policies for the VPLS network interface.

   For instructions, see Configuring Subscriber Policies for VPLS Network Interfaces.

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.

6. Configure MPLS LSPs to connect local and remote PE routers.

   For instructions, see Configuring MPLS LSPs for VPLS.

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.
