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:
1. Enable BFD globally.
2. Establish sessions with OSPFv3 neighbors.

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 Displaying BFD for BGP Information.
