Enabling an MPLS Device to Dynamically Establish a BFD Session

Enabling an MPLS Device to Dynamically Establish a BFD Session

A dynamic BFD session that monitors both the primary and FRR LSPs can be established only after an MPLS device is enabled to dynamically establish the BFD session.

Procedure

  • Perform the following steps on the ingress:
    1. Run system-view

      The system view is displayed.

    2. Run bfd

      BFD is globally enabled.

    3. Run quit

      The system view is displayed.

    4. Run mpls

      The MPLS view is displayed.

    5. Run mpls bfd enable

      The capability of dynamically establishing a BFD session is configured on the ingress.

      The mpls bfd enable command does not create a BFD session.

    6. Run commit

      The configuration is committed.

  • Perform the following steps on the egress:
    1. Run system-view

      The system view is displayed.

    2. Run bfd

      BFD is globally enabled, and the BFD view is displayed.

    3. Run mpls-passive

      The capability of passively creating a BFD session is configured on the egress.

      The mpls-passive command does not create a BFD session. The egress has to receive an LSP ping request carrying a BFD TLV before creating a BFD session with the ingress.

    4. Run commit

      The configuration is committed.
