BFD for static routes configuration example (direct next hop)
Network requirements
As shown in Figure 4, configure static routes to subnet 120.1.1.0/24 on Switch A, static routes to subnet
121.1.1.0 / 24 o n Swi t c h B , a n d s t a t i c ro u t e s t o s u b n e t s 12 0 .1.1.0 / 24 a n d 121.1.1.0 / 24 o n Sw i t c h C .
Enable BFD so that when the link between Switch A and Switch B through the Layer 2 switch fails, BFD
can detect the failure immediately and Switch A and Switch B can communicate through Switch C.
