Bfd For Static Routes Configuration Example (Direct Next Hop) - HPE FlexNetwork HSR6800 Configuration Manual

BFD for static routes configuration example (direct next hop)

Network requirements
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, and 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.
