Configuring Manual FRR for a Manually Configured P2MP TE Tunnel

Procedure

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

     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 commit

     The configuration is committed.

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

     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 commit

      The configuration is committed.
