Configuring a Failure Action for the BFD Session on an LDP LSP

You can configure route and next-hop properties in the event of a BFD session failure event on an LDP LSP. The failure event could be an existing BFD session that has gone down or could be a BFD session that never came up. LDP adds back the route or next hop when the relevant BFD session comes back up.

You can configure one of the following failure action options for the failure-action statement in the event of a BFD session failure on the LDP LSP:

• remove-nexthop—Removes the route corresponding to the next hop of the LSP's route at the ingress node when a BFD session failure event is detected.
• remove-route—Removes the route corresponding to the LSP from the appropriate routing tables when a BFD session failure event is detected. If the LSP is configured with ECMP and a BFD session corresponding to any path goes down, the route is removed.
