Example for Associating E-VRRP with 4PE PW Redundancy

In 4PE PW redundancy scenarios, the mVRRP status determines the master/backup status of PEs.

Networking Requirements

On the network shown in Figure 1, PE1 and PE2 are connected over a bypass PW, and PE3 and PE4 are connected over another bypass PW. To allow communication between CEs and PEs in case a public network link or a PE fails, associate E-VRRP with 4PE PW redundancy.

  • Interfaces 1 through 4 in this example represent GE 0/1/0, GE 0/1/1, GE 0/1/2, and GE 0/1/3, respectively.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure IP addresses and a routing protocol and enable MPLS on the PEs.

  2. Configure public network tunnels.

  3. Configure service PWs.

  4. Configure BFD for PW to detect PW connectivity.

  5. Determine the VRRP master/backup status.

Data Preparation

To complete the configuration, you need the following data:

  • Interface numbers and types

  • PE's LSR IDs

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

  • BFD session name and local and remote BFD session discriminators

  • VRRP group ID and priority

Procedure

  1. Assign an IP address to each interface and configure a routing protocol.

    Configure the IP address and mask for each interface based on Figure 1.

    IS-IS is used in this example. For configuration details, see Configuration Files in this section.

  2. Configure public network tunnels.
    1. Enable MPLS, MPLS TE, and RSVP-TE on each PE.

      Repeat this step for PE2, PE3, and PE4. For configuration details, see Configuration Files in this section.

    2. Create VCs.

      [~PE1] interface gigabitethernet 0/1/0.1

    Repeat this step for PE2, PE3, and PE4. For configuration details, see Configuration Files in this section.

  5. Determine the VRRP master/backup status.
    1. Configure mVRRP to determine the master/backup status of the PEs.

      # Configure PE1.

      [~PE1] interface gigabitethernet 0/1/0.2
[*PE1-GigabitEthernet0/1/0.2] vlan-type dot1q 2
[*PE1-GigabitEthernet0/1/0.2] ip address 10.1.1.1 24

[*PE1] commit

      # Verify the configuration. Run the display vrrp command on PE1 and PE2 to check the master/backup status of them. The following example uses the command output on PE1. As PE1 has the VRRP priority of 120 and PE2 has the default VRRP priority of 100, the VRRP status of PE1 is Master.

      [*PE1] display vrrp

    2. Bind the service PWs to the mVRRP group.

      # Configure PE1.

      [~PE1] interface gigabitethernet 0/1/0.1
[~PE1-GigabitEthernet0/1/0.1] mpls l2vc track admin-vrrp interface gigabitethernet 0/1/0.2 vrid 1 pw-redundancy
[*PE1-GigabitEthernet0/1/0.1] mpls l2vc track admin-vrrp secondary
[*PE1-GigabitEthernet0/1/0.1] quit
[*PE1] commit

      Repeat this step for PE2, PE3, and PE4. For configuration details, see Configuration Files in this section.

  6. Verify the configuration.
    1. Ping the virtual IP address of a service VRRP group from a CE. The ping is successful.

      [~CE1] ping 10.1.1.254
PING 10.1.1.254: 56  data bytes, press CTRL_C to break
    Reply from 10.1.1.254: bytes=56 Sequence=1 ttl=255 time=40 ms

    Reply from 10.1.1.254: bytes=56 Sequence=5 ttl=255 time=1 ms

  --- 10.1.1.254 ping statistics ---
    5 packet(s) transmitted
    5 packet(s) received
    0.00% packet loss
    round-trip min/avg/max = 1/22/40 ms

    2. Simulate an interface fault and an interface fault recovery.

      # Disable GE 0/1/0 on PE1 to simulate an AC interface fault.

      [~PE1] interface gigabitethernet 0/1/0
[~PE1-GigabitEthernet0/1/0] shutdown
[*PE1-GigabitEthernet0/1/0] quit
[*PE1] commit

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

      As the primary AC interface fails, the upstream traffic is transmitted along the path CE1 -> PE2 -> PE3 -> CE2. Run the display mpls l2vc track admin-vrrp command on PE1. The command output shows that the VRRP status is Initialize.

      [~PE1] display mpls l2vc track admin-vrrp
