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