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. 144
