Disabling and re-enabling BFD
BFD is enabled on all interfaces by default, though sessions are not created unless explicitly configured. If
BFD is disabled, all of the sessions on that interface are placed in an Administratively Down state
(Message 2), and the remote systems are notified of the session state change
To disable BFD on an interface:
Step Task
1 Disable BFD on an interface.
Message 2 Disabling BFD on a Local Interface
