Configuring BFD Support for Static Routes
This section provides information about how to configure and verify BFD support for static routing.
To change the default BFD status for a particular static route and to enable BFD support, use the
route bfd-state command. For example :
-> ip static-route 10.1.1.1 mask 255.0.0.0 gateway 10.1.1.25 bfd-state enable
Note. Static Routes support BFD in the echo-only operational mode.
The above command enables BFD support for a static route with destination ip address as 10.1.1.1, desti-
nation network mask as 255.0.0.0, and gateway address as 10.1.1.25.
In order to create a BFD session for a static route, the gateway address should not match with any local
interface address of the switch. If multiple routes are configured with the same gateway address, only one
BFD session is run. You can verify the BFD session list which shows the gateway address using the
ip bfd sessions command.
To enable BFD support for all static routes, use the
-> ip static-route all bfd-state enable
To verify the static routes on which BFD is enabled, use the
protocol static option. For example:
-> show ip router database protocol static
