Configuring VPLS PW Redundancy

Configuring VPLS PW Redundancy

Pre-configuration Tasks

Before configuring VPLS PW redundancy, complete the following tasks:

  • Configure IP addresses and an Interior Gateway Protocol (IGP) on PEs.

  • Establish public tunnels between PEs.

    The public tunnels can be:

    • LDP tunnels: To establish LDP tunnels, you must enable MPLS and MPLS LDP globally and in the interface view on each node of the public network. If two PEs are indirectly connected, establish a remote LDP session between them.

    • TE tunnels: To establish TE tunnels, you must enable MPLS, MPLS TE, and RSVP-TE globally and in the interface view on each node of the public network, and enable CSPF in the MPLS view of the ingress of each tunnel to be created.

      NOTE:

      Because pseudo wire emulation edge-to-edge (PWE3) uses LDP to distribute VPN labels, you must globally enable MPLS LDP on PEs and establish MPLS LDP sessions if TE tunnels are used as public tunnels.

      If the public tunnels are not LDP tunnels, you must configure tunnel policies and apply them to these public tunnels.

      Only the VPLSs in PWE3 mode support PW redundancy.

  • Enable MPLS L2VPN on PEs.

Configuration Process

To configure VPLS PW Redundancy, perform the following configurations on the PE. Configuring BFD for PW and Manually Switching PWs in a PW Protection Group are optional.
