Enabling the Capability of Dynamically Creating BFD Sessions on the Ingress

Procedure

• Enable MPLS TE BFD globally.
  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 is enabled on all the tunnel interfaces, excluding the interfaces on which dynamic BFD for TE 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.
     1. Run quit

        Return to the system view.

     2. Run interface tunnel interface-number

        The TE tunnel interface view is displayed.

     3. Run mpls te bfd block

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

     4. Run mpls te commit

        The current configuration on this tunnel interface is committed.

• Enable MPLS TE BFD on a tunnel interface.
  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 mpls te commit

     The configuration of the TE tunnel is committed.
