VPLS-LDP VPN

The VPLS-LDP VPN, based on the IETF Lasserre/Kompella draft, is implemented by Cisco and all other vendors except Juniper. To configure a VPLS-LDP VPN, perform the following steps:

  1. First identify, for the VPLS-LDP, a set of PEs with available PE-facing-CE interfaces that can be assigned as VPLS attachment circuits.
  2. Next, bring up the Add VPN window and select VPLS-LDP VPN. In this example, we will configure a VPLS instance named VPLS-LDP0.

  3. Click on Next to take you to the screen to specify a VCID and to select the PEs for the VPLS instance, as shown in the following screen. If you prefer, you may select some or all the PEs in the PE Selection tab in the next screen, as described in the next step. Click on Next to continue.

  4. As described in the previous step, you may select PEs in the PE Selection tab, as shown in the following screen. If you have already selected all the PEs in the previous step, then click on the Details tab to continue.

Selected Objects: GV1, GV2, V_C1 with no interface. Available Devices: EP_R9, ESV_1, E_V1, E_V2, E_V3. Properties section for configuration. Finish, Cancel, Help buttons at the bottom.
  5. Next, you are ready to configure the PE-facing-CE attachment circuits; this includes specifying the interface and circuit ID, bandwidth, and encapsulation.

    The encapsulation types for various vendors are:

    • Cisco: dot1qaccess, dot1qtunnel, dot1qtrunk.

    • Foundry: tagged, untagged.

    • Tellabs, Riverstone: tagged, untagged, q-in-q.

    The following figures show how an interface is assigned: First, click on the magnifying glass next to Interfaces and choose Add. Then in the Select Interface window, pick an available interface. Finally, type in the VCID for the interface

  6. Next, you will specify, in turn, each remote peer and the transmit LSP used to reach the peer. Click on the magnifying glass next to Remote Peers to bring up the Add Remote Peer window, where you can choose the remote peer and the transmit LSP from the dropdown selection menus.
