When VLAN-interface 3 recovers, switch A will resume its gateway function as the master.
Multiple-VRRP Group Configuration
Network requirements
A switch can function as a backup of multiple VRRP groups.
Multiple-VRRP group configuration can implement load balancing. For example, Switch A acts as the
master of VRRP group 1 and a backup in VRRP group 2. Similarly, Switch B acts as the master of VRRP
group 2 and a backup in VRRP group 1. Some hosts in the network take virtual router 1 as the gateway,
while others take virtual router 2 as the gateway. In this way, both load balancing and mutual backup are
implemented.
