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
BGP Information.
• Change parameters for all OSPFv3 sessions.
ROUTER-OSPFv3 mode
bfd all-neighbors interval milliseconds min_rx milliseconds multiplier value role [active
| passive]
• Change parameters for OSPFv3 sessions on a single interface.
INTERFACE mode

role [active | passive]
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

Configure BFD for OSPFv3

BFD for OSPFv3 provides support for IPV6.
Configuring BFD for OSPFv3 is a two-step process:
