Example for Configuring 3PE PW Redundancy When CEs Are Asymmetrically Connected to PEs on Mobile Bearer Networks

In PW redundancy scenarios in which CEs are asymmetrically connected to PEs, the E-Trunk determines the master/backup status of the PEs.

Networking Requirements

On the network shown in Figure 1, CE1 and CE2 are users of the same enterprise, and PE1 through PE3 are public network devices. CE1 is single-homed to PE1, and CE2 is dual-homed to PE2 and PE3. To allow CE1 and CE2 to communicate and also ensure reliability, deploy PW redundancy between PE1, PE2, and PE3 to protect PWs. In addition, to rapidly detect public network link faults to implement fast PW switching, deploy BFD.

  • Interfaces 1 through 3 in this example represent GE 0/1/0, GE0/1/1, and GE 0/1/2, respectively.


Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure an IP address and a routing protocol for each interface to ensure IP connectivity at the network layer. OSPF is used in this example.

  2. Configure MPLS and public network tunnels.

  3. Configure service PWs and mPWs, and bind the service PWs to the mPWs.

  4. Configure BFD to detect mPW connectivity.

  5. Configure an E-Trunk to determine the master/backup status of the PWs, and bind BFD to the E-Trunk.

Data Preparation

To complete the configuration, you need the following data:

  • PEs' interface numbers, IP addresses and OSPF process IDs

  • PE's LSR IDs

  • E-Trunk's LACP system IDs and priorities

  • L2VC's destination IP addresses, VC IDs, and VC types

  • BFD session name and local and remote BFD session discriminators

Procedure

  1. Configure an IP address and a routing protocol for each interface to ensure IP connectivity at the network layer.

    For configuration details, see Configuration Files in this section.

  2. Configure basic MPLS functions. Configure a TE tunnel between PE1 and PE2 and between PE1 and PE3; configure an LDP LSP between PE2 and PE3.

    For configuration details, see Configuration Files in this section.

  3. Configure PWE3.
    1. Configure a remote LDP session between PE1 and PE2 and between PE1 and PE3.

      For configuration details, see Configuration Files in this section.

      PWE3 uses extended LDP signaling to distribute VC labels. Because PE1 and PE2 and PE1 and PE3 are connected over TE tunnels without using MPLS LDP, you must globally enable MPLS LDP and establish remote LDP sessions.

      PE2 and PE3 are directly connected over an LDP LSP, and therefore do not need to establish a remote LDP session.

    2. Configure service PWs.

  6. Verify the configuration.
    1. Run the display bfd session all command on a PE to check whether the BFD session is Up. The following example uses the command output on PE1.

      [~PE1] display bfd session all

    3. Run the display mpls l2vc command on a PE to check whether the VC status is Up. The following example uses the command output on PE1.

      [~PE1] display mpls l2vc
 Total LDP VC : 4     4 up       0 down

    5. Simulate a fault and a fault recovery.

      Simulate a public network link fault between PE2 and PE1.

      # Disable GE 0/1/0 on PE2 to simulate a fault on the primary PW.

      This step is used only to verify the configuration. Do not do this in practice.

      Then run the display mpls l2vc command on PE1. The command output shows that the VC status of the mPW and service PW between PE1 and PE2 is down and the VC status of the mPW and service PW between PE1 and PE3 is up.

      # Enable GE 0/1/0 on PE2 to simulate a link fault recovery of the primary PW.

      [~PE2] interface gigabitethernet 0/1/0
[~PE2-GigabitEthernet0/1/0] undo shutdown
[*PE2-GigabitEthernet0/1/0] quit
[*PE2] commit

      The link that bears the primary PW has restored, but it takes a period of time for the primary PW to be established. Therefore, traffic still travels along the secondary PW. After the primary PW is established, run the display mpls l2vc command on PE1. The command output shows that the VC status of the mPW and service PW between PE1 and PE2 has become up.
