• Disable BFD sessions with OSPFv3 neighbors on a single interface.

Establishing Sessions with OSPFv3 Neighbors
You can establish BFD sessions with all OSPFv3 neighbors at once or with all neighbors out of a specic 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.
Congure 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 on the line card noties the BFD manager, which in turn
noties the IS-IS protocol that a link state change occurred.
Conguring BFD for IS-IS is a two-step process:
1 Enable BFD globally.
2 Establish sessions for all or particular IS-IS neighbors.
