Configuring BFD for RIP (single-hop detection in BFD echo
packet mode) at the CLI
Network requirements
As shown in Figure 251 :
• SecPath A and Router C are interconnected through a Layer 2 switch. GigabitEthernet 0/1 of the
two routers runs RIP process 1, BFD is enabled on GigabitEthernet 0/1 of Router A.
• SecPath A is connected to Router C through Router B. GigabitEthernet 0/2 on SecPath A runs RIP
process 2. GigabitEthernet 0/2 on Router C, and GigabitEthernet 0/1 and GigabitEthernet 0/2
on Router B run RIP process 1.
• Configure a static route and enable static route redistribution into RIP on Router C. SecPath A learns
the static route sent by Router C, and the output interface of the route is the interface connected to
the Layer 2 switch.
• When the link between Router C and the Layer 2 switch fails, BFD can quickly detect the link failure
and notify it to RIP, and the BFD session goes down. In response, RIP deletes the neighbor
relationship with Router C and the route information received from Router C. Then, SecPath A learns
the static route from Router C with the output interface being the interface connected to Router B.
