Configuring Protocol Liveness
Protocol liveness is a feature that notifies the BFD manager when a client protocol is disabled.
When you disable a client, all BFD sessions for that protocol are torn down. Neighbors on the remote
system receive an Admin Down control packet and are placed in the Down state.
To enable protocol liveness, use the following command.
• Enable Protocol Liveness.
