BFD for static routes configuration example (direct next hop)

Network requirements

As shown in Figure 3:

• Configure a static route to subnet 120.1.1.0/24 on Router A.

• 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

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.
