Enabling Dynamic BFD Session Creation over an LDP LSP

Procedure

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

     The system view is displayed.

  2. Run mpls

     The MPLS view is displayed.

  3. Run mpls bfd enable

     BFD is enabled on the ingress.

     

     After this step is complete, a BFD session can be established when the egress is configured and the ingress sends LSP PIng Request packets carrying BFD TLV objects.

  4. 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

     The BFD view is displayed.

  3. Run mpls-passive

     The egress is enabled to create a BFD session passively.

     

     After this step is complete, a BFD session will be established dynamically when the egress receives an LSP Ping Request packet carrying a BFD TLV field from the ingress.

  4. Run commit

     The configuration is committed.
