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 load balancing mode to make good use of network resources.
