Three routers RTA, RTB, and RTC are connected together through a LAN to form a VRRP backup group. The interface configuration of each router is as follows:
RTA's GigabitEthernet
IP address 192.168.0.252 255.255.255.0
Vrrp vrid 1 virtual-ip 192.168.0.254
Vrrp vrid 1 priority 120 RTB GigabitEthernet
IP address 192.168.0.253 255.255.255.0
Vrrp vrid 1 virtual-ip 192.168.0.254
Vrrp vrid 1 priority 90 RTC GigabitEthernet
IP address 192.168.0.254 255.255.255.0
Vrrp vrid 1 virtual-ip 192.168.0.254
