Disabling BFD for OSPFv3
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 final Admin
Down packet is sent before the session is terminated.
To disable BFD sessions, use the following commands.
• Disable BFD sessions with all OSPFv3 neighbors.
ROUTER-OSPFv3 mode
no bfd all-neighbors
• Disable BFD sessions with OSPFv3 neighbors on a single interface.
INTERFACE mode
ipv6 ospf bfd all-neighbors disable
Establishing Sessions with OSPFv3 Neighbors
You can establish BFD sessions with all OSPFv3 neighbors at once or with all neighbors out of a specific
interface. Sessions are only established when the OSPFv3 adjacency is in the Full state.
To establish BFD with all OSPFv3 neighbors or with OSPFv3 neighbors on a single interface, use the following
commands.
• Establish sessions with all OSPFv3 neighbors.
ROUTER-OSPFv3 mode
bfd all-neighbors
• Establish sessions with OSPFv3 neighbors on a single interface.
INTERFACE mode
ipv6 ospf bfd all-neighbors
To view the established sessions, use the show bfd neighbors command.

Configure BFD for IS-IS

When using BFD with IS-IS, the IS-IS protocol registers with the BFD manager. BFD sessions are then
established with all neighboring interfaces participating in IS-IS. If a neighboring interface fails, the BFD agent
