Configuring BFD for Static Routes

BFD gives systems a link state detection mechanism for static routes. With BFD, systems are notified to
remove static routes from the routing table as soon as the link state change occurs, rather than having to
wait until packets fail to reach their next hop.
Configuring BFD for static routes is a three-step process:
1. Enable BFD globally. See
2. On the local system, establish a session with the next hop of a static route. See page 180.
3. On the remote system, establish a session with the physical port that is the origin of the static route.
See

Disable BFD for all static routes. See page 181.
Establishing sessions for static routes
Sessions are established for all neighbors that are the next hop of a static route.
