Configuring Manual FRR for a Manually Configured P2MP TE Tunnel

Configuring Manual FRR for a Manually Configured P2MP TE Tunnel

Manual FRR can be configured on the tunnel interface of a manually configured P2MP TE tunnel.


The process of configuring P2MP TE FRR is identical to that for configuring P2P TE FRR, which includes the following two procedures:

Manual P2MP TE FRR only applies to manual P2MP TE tunnels.


  • Enable the P2MP TE FRR function on the tunnel interface of the primary tunnel (P2MP TE tunnel).
    1. Run:


      The system view is displayed.

    2. Run:

      interface tunnel interface-number

      The MPLS TE tunnel interface view is displayed.

    3. Run:

      mpls te fast-reroute [ bandwidth ]

      The P2MP TE FRR function is enabled.


      You can run the mpls te bypass-attributes command to configure bypass tunnel attributes only after running the mpls te fast-reroute bandwidth command.

    4. (Optional) Run:

      mpls te bypass-attributes

      Bypass tunnel attributes are configured.

    5. Run:


      The configuration is committed.

  • Configure a bypass tunnel on the PLR node and bind the bypass tunnel to the primary tunnel.
    1. Run:


      The system view is displayed.

    2. Run:

      interface tunnel tunnel-number

      The tunnel interface view of a bypass tunnel is displayed.

    3. Run:

      tunnel-protocol mpls te

      MPLS TE is configured as a tunnel protocol.

    4. Run:

      destination ip-address

      The LSR ID of a merge point (MP) is specified as the destination address of the bypass tunnel.

    5. Run:

      mpls te tunnel-id tunnel-id

      The bypass tunnel ID is specified.

    6. (Optional) Run:

      mpls te path explicit-path path-name

      An explicit path is specified for the bypass tunnel.


      The explicit path planned for the bypass tunnel and the primary tunnel path to be protected must use different physical links.

    7. (Optional) Run:

      mpls te bandwidth ct0 bandwidth

      The bypass tunnel bandwidth is configured.

    8. Run:

      mpls te bypass-tunnel

      A bypass tunnel is configured.

    9. Run:

      mpls te protected-interface interface-type interface-number

      A link interface to be protected by a bypass tunnel is specified.

    10. Run:


      The configuration is committed.
