The above information indicates that in VRRP group 1 Switch A is the master, Switch B is the backup
and hosts with the default gateway of 202.38.160.100/25 accesses the Internet through Switch A; in
VRRP group 2 Switch A is the backup, Switch B is the master and hosts with the default gateway of
202.38.160.200/25 accesses the Internet through Switch B.
VRRP Load Balancing Mode Configuration Example
Network requirements
Switch A, Switch B, and Switch C belong to VRRP group 1 with the virtual IP address of
10.1.1.1/24.
Hosts on network segment 10.1.1.0/24 use 10.1.1.1/24 as their default gateway. Use the VRRP
group to ensure that when a gateway (Switch A, Switch B, or Switch C) fails, the hosts on the LAN
can access the external network through another gateway.
VRRP group 1 works in the load balancing mode to make good use of network resources.
