As shown in Figure 1-2, make sure the routes between Switch A, Switch B, and Switch C, and between Switch A, Switch D, and Switch C are reachable.

Create detected group 10 on Switch A to detect the connectivity between Switch B and Switch C. Configure VLAN-interface 1 to be the active interface, which is enabled when the detected group

10is reachable.

Configure VLAN-interface 2 to be the standby interface, which is enabled when the detected group 10 is unreachable.
