Example of configuring VRRP active/standby backup on an AR router

The roadmap of configuring VRRP active/standby backup on an AR router to implement gateway redundancy is as follows:
1. Configure IP addresses and routing protocols for different device interfaces to enable network-layer connection among different devices.
2. Configure a VRRP group on Router A and Router B, respectively. Configure a high priority and set preemption delay to 20s on Router A and configure Router A as a master device to bear and forward traffic. Configure a low priority and configure Router B as a backup device to implement gateway redundancy.
Configure a VRRP group.
# Create VRRP 1 on Router A, set its priority to 120, and set the preemption delay to 20s.
[RouterA] interface gigabitethernet 2/0/0
[RouterA-GigabitEthernet2/0/0] vrrp vrid 1 virtual-ip 10.1.1.111 //Configure a virtual IP address.
[RouterA-GigabitEthernet2/0/0] vrrp vrid 1 priority 120 //Set priority to 120.
[RouterA-GigabitEthernet2/0/0] vrrp vrid 1 preempt-mode timer delay 20 //Set the preemption delay to 20s.
[RouterA-GigabitEthernet2/0/0] quit
# Create VRRP 1 on Router B, and set its priority to a default value 100.
[RouterB] interface gigabitethernet 2/0/0
[RouterB-GigabitEthernet2/0/0] vrrp vrid 1 virtual-ip 10.1.1.111
[RouterB-GigabitEthernet2/0/0] quit
