The output shows 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
make sure that when a gateway (Switch A, Switch B, or Switch C) fails, the hosts on the LAN can access
external networks through another gateway.
VRRP group 1 is operating in load balancing mode to make good use of network resources.
Configure a track entry on Switch A, Switch B, and Switch C to monitor their own VLAN-interface 3.
When the interface on Switch A, Switch B, or Switch C fails, the weight of the corresponding switch
decreases so that another switch with a higher weight can take over.
