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 neighbors command output for default VRF.
