When VLAN 3 interface recovers, switch A will resume its gateway function as the
master.
1.4.3 Multiple-VRRP Backup Group Configuration
I. Network requirements
A switch can function as backup switches of multiple backup groups.
Multiple-backup group configuration can implement load balancing. For example,
Switch A operates as the master switch of backup group 1 and a backup switch in
backup group 2. Similarly, Switch B operates as the master switch of backup group 2
and a backup switch in backup 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.
