Figure 4-13, the networking requirements are as follows:
Switch A, Switch B, and Switch C run OSPF.
BFD for OSPF is enabled on Switch A, Switch B, and Switch C.
Service traffic is transmitted on the main link Switch A→Switch B. Link Switch A→Switch
C→Switch B is a backup link.
BFD is configured on the interfaces between Switch A and Switch B. When a fault occurs
on the link between the Switch s, BFD can quickly detect the fault and notify OSPF of the
fault. Then, the service flow is transmitted on the backup link.
