RIP FRR configuration example 
Network requirements 
Switch S, Switch A, and Switch D are interconnected through RIPv2, as illustrated in  Figure 14. C onfigure 
RIP FRR so that when Link A between Switch S and Switch D fails, services can be switched to Link B 
immediately.

Configure a static route and enable static route redistribution into RIP on Switch C. Switch A learns the 
static route sent by Switch C, the outbound interface of the route is the interface connected to the Layer 
2 switch.  
Configure BFD so that when the link between Switch 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 Switch C and the route information received...
