Congure BFD for IPv6 Static Routes
BFD oers systems a link state detection mechanism for static routes. With BFD, systems are notied to remove static routes from the
routing table as soon as the link state change occurs, rather than waiting until packets fail to reach their next hop.
Conguring BFD for IPv6 static routes is a three-step process:
1 Enable BFD globally.
2 Congure static routes on both routers on the system (either local or remote).
3 Congure an IPv6 route to connect BFD on the static routes using the ipv6 route bfd command.

Establishing Sessions for IPv6 Static Routes for Default VRF
Sessions are established for all neighbors that are the next hop of a static route on the default VRF.
To establish a BFD session, use the following command.
• Establish BFD sessions for all IPv6 neighbors that are the next hop of a static route.
CONFIGURATION mode
ipv6 route bfd [prefix-list prefix-list-name] [interval interval min_rx min_rx multiplier
value role {active | passive}]
Example of the show bfd neighbors Command to Verify Static Routes
To verify that sessions have been created for static routes, use the show bfd neighbors command.
To view detailed session information, use the show bfd neighbors detail command, as shown in the examples in Displaying BFD
for BGP Information
.
Establishing Sessions for IPv6 Static Routes for Nondefault VRF
You can also create nondefault VRFs and establish sessions for all neighbors that are the next hop of a static route.
To establish a BFD session for nondefault VRFs, use the following command.
• Establish BFD sessions for all IPv6 neighbors that are the next hop of a static route.
CONFIGURATION mode
ipv6 route bfd vrf vrf-name [prefix-list prefix-list-name] [interval interval min_rx min_rx
multiplier value role {active | passive}]
Example Conguration and Verication
The following example contains static routes for both default and nondefault VRFs.
