Example for Configuring Interworking Between LDP VPLS and BGP AD VPLS in PW Redundancy Mode

This section provides an example of configuring interworking between Label Distribution Protocol (LDP) virtual private LAN service (VPLS) and Border Gateway Protocol Auto-Discovery (BGP AD) VPLS in pseudo wire (PW) redundancy mode.

Networking Requirements

As shown in Figure 1, PE1 supports LDP VPLS, PE4 supports BGP AD VPLS, and PE2 and PE3 support both LDP VPLS and BGP AD VPLS. It is required that interworking between LDP VPLS and BGP AD VPLS be configured in PW redundancy mode for CE1 and CE2 to communicate.

The specific PW deployment requirements are as follows:
  • Establish a hub PW from PE1 to PE2 and from PE1 to PE3. The two PWs work in master/slave PW redundancy mode.
  • Establish an LDP spoke PW from PE2 to PE1. Establish a BGP AD hub PW from PE2 to PE3 and from PE2 to PE4.
  • Establish an LDP spoke PW from PE3 to PE1. Establish a BGP AD hub PW from PE3 to PE2 and from PE3 to PE4.
  • Establish a BGP AD hub PW from PE4 to PE2 and from PE4 to PE3.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure an IP address and a routing protocol for each interface so that all PEs can communicate at the network layer.

  2. Configure Multiprotocol Label Switching (MPLS) and public tunnels.

  3. Configure PE1, PE2, and PE3 to form an LDP VPLS network.

  4. Configure PE2, PE3, and PE4 to form a BGP AD VPLS network.

  5. Configure PW redundancy (master/slave) on PE1.

  6. Configure Media Access Control (MAC) Withdraw.

Data Preparation

To complete the configuration, you need the following data:

  • IP address, Open Shortest Path First (OSPF) process ID, and OSPF area ID of each interface, and label switching router (LSR) ID of each PE

  • Virtual switch instance (VSI) name, VSI ID, VPLS ID, virtual private network (VPN) targets, and BGP AS number

  • Number and virtual local area network (VLAN) ID of each interface bound to a VSI

  • PW redundancy protection group name, revertive switching mode, revertive switching delay, and PW priorities

Procedure

  1. Configure an IP address and a routing protocol for each interface on the backbone network so that PEs can communicate at the network layer.

    This example uses OSPF as the routing protocol. For details about specific configurations, see the following configuration files.

    After the configuration is complete, run the display ip routing-table command on PEs to verify that the PEs have learned each other's loopback interface IP address.

  2. Configure MPLS and public tunnels.

    This example uses LDP LSPs as public tunnels. For details about specific configurations, see the following configuration files.

    After the configuration is complete, run the display mpls ldp session command on PEs to verify that peer relationships have been established; run the display mpls lsp command to verify that LSPs have been established.

  3. Configure PE1, PE2, and PE3 to form an LDP VPLS network.

  5. Configure PW redundancy (master/slave) on PE1.

    1. Configure a PW protection group on PE1 and specify the PW redundancy mode as master/slave. Add the hub PWs from PE1 to PE2 and PE3 to the PW protection group, specify the priorities of the PWs, and set the revertive switching delay to 60s.

      [~PE1] vsi vsi1

    2. Configure Bidirectional Forwarding Detection (BFD) for PW to monitor the primary PW.

      # Configure PE1.
