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.
Changing OSPFv3 Session Parameters
Configure BFD sessions with default intervals and a default role.
The parameters that you can configure are: desired tx interval, required min rx interval, detection multiplier,
and system role. Configure these parameters for all OSPFv3 sessions or all OSPFv3 sessions on a particular interface. If you change a
parameter globally, the change affects all OSPFv3 neighbors sessions. If you change a parameter at the interface level, the change affects
all OSPFv3 sessions on that interface.
To change parameters for all OSPFv3 sessions or for OSPFv3 sessions on a single interface, use the following commands.
To view session parameters, use the show bfd neighbors detail command, as shown in the example in
Information.
• Change parameters for all OSPFv3 sessions.

• Change parameters for OSPFv3 sessions on a single interface.
