2.4.2 Configuration Example
I. Network requirements
z Configure a static route between Switch C and Switch A.
z Create detecting group 10 on Switch A to detect the connectivity between Switch
B and Switch C.
z Configure VLAN 1 interface to be the primary interface, which is enabled when the
result of detecting group 10 is reachable.
z Configure VLAN 2 interface to be the secondary interface, which is enabled when
the result of the detecting group 10 is unreachable.
z Make sure the routes between Switch A, Switch B, and Switch C are reachable;
and those between Switch A, Switch D, and Switch C are also reachable.
