• In VRRP group 1, Switch A has a higher priority than Switch B. In VRRP group 2, Switch B has a
higher priority than Switch A. In this case, hosts in VLAN 1 and VLAN can communicate with
external networks through Switch A and Switch B respectively, and when Switch A or Switch B fails,
the hosts can use the other switch to communicate with external networks to avoid communication
interruption.
