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.
The following example shows the show bfd vrf neighbors command output for default VRF.
