Figure 1-6 VRRP in load balancing mode
A switch can be in multiple standby groups and hold a different priority in different
group.
In Figure
Standby group 1: Switch A is the master; Switch B and Switch C are the backups.
Standby group 2: Switch B is the master; Switch A and Switch C are the backups.
Standby group 3: Switch C is the master; Switch A and Switch B are the backups.
For load balancing among Switch A, Switch B, and Switch C, hosts on the LAN need to
be configured to use standby group 1, 2, and 3 as the default gateways respectively.
When configuring VRRP priorities, ensure that each switch holds such a priority in each
standby group that it will take the expected role in the group.
