Disabling BFD for OSPF
If you disable BFD globally, all sessions are torn down and sessions on the remote system are placed in a Down state.
If you disable BFD on an interface, sessions on the interface are torn down and sessions on the remote system are placed in a Down state.
Disabling BFD does not trigger a change in BFD clients; a nal Admin Down packet is sent before the session is terminated.
To disable BFD sessions, use the following commands.
• Disable BFD sessions with all OSPF neighbors.
ROUTER-OSPF mode
no bfd all-neighbors
• Disable BFD sessions with all OSPF neighbors on an interface.
INTERFACE mode
ip ospf bfd all-neighbors disable
