BFD for static routes configuration example (direct next hop)
Network requirements
, configure a static route to subnet 120.1.1.0/24 on Router A, and configure a static route to
subnet 121.1.1.0/24 on Router B. Enable BFD for both routes. Configure a static route to subnet
120.1.1.0/24 and a static route to subnet 121.1.1.0/24 on Router C. When the link between Router A and
Router B through the Layer 2 switch fails, BFD can detect the failure immediately and inform Router A and
Router B to communicate through Router C.
