Enabling the Capability of Dynamically Creating BFD Sessions on the Ingress

Enabling the Capability of Dynamically Creating BFD Sessions on the Ingress

You can enable the ingress node to dynamically create BFD sessions on a TE tunnel either globally or on a specified tunnel interface.

Context

Perform either of the following operations:

Procedure

  • Enable MPLS TE BFD globally on the ingress.
    1. Run system-view

      The system view is displayed.

    2. Run mpls

      The MPLS view is displayed.

    3. Run mpls te bfd enable

      The capability of dynamically creating BFD sessions is enabled on the TE tunnel.

      After this command is run in the MPLS view, dynamic BFD for TE LSP is enabled on all tunnel interfaces, excluding the interfaces on which dynamic BFD for TE LSP is blocked.

    4. (Optional) Block the capability of dynamically creating BFD sessions for TE on the tunnel interfaces of the TE tunnels that do not need dynamic BFD for TE LSP.

      1. Run interface tunnel interface-number

        The TE tunnel interface view is displayed.

      2. Run mpls te bfd block

        The capability of dynamically creating BFD sessions on the tunnel interface is blocked.

    5. Run commit

      The configuration is committed.

  • Enable MPLS TE BFD on a tunnel interface of the ingress.
    1. Run system-view

      The system view is displayed.

    2. Run interface tunnel interface-number

      The TE tunnel interface view is displayed.

    3. Run mpls te bfd enable

      The capability of dynamically creating BFD sessions is enabled on the TE tunnel.

      The command configured in the tunnel interface view takes effect only on the current tunnel interface.

    4. Run commit

      The configuration is committed.
