[RouterA] interface ethernet 1/1

[RouterA-Ethernet1/1] vrrp vrid 1 virtual-ip 10.1.1.10

# Set the priority of Router A in VRRP group 1 to 110.

[RouterA-Ethernet1/1] vrrp vrid 1 priority 110

# Configure to monitor track entry 1 and specify the priority decrement as 30.

[RouterA-Ethernet1/1] vrrp vrid 1 track 1 reduced 30

4. Configure VRRP on Router B:

<RouterB> system-view

[RouterB] interface ethernet 1/1

# Create VRRP group 1, and configure the virtual IP address 10.1.1.10 for the group.

[RouterB-Ethernet1/1] vrrp vrid 1 virtual-ip 10.1.1.10
