Configure a track entry on Router A, Router B, and Router C to monitor their own Ethernet 1/2.

When the interface on Router A, Router B, or Router C fails, the weight of the corresponding router
decreases so that another router with a higher weight can take over.

Configure track entries on Router C to monitor Router A and Router B. When Router A or Router B
fails, Router C immediately takes over the AVF on Router A or Router B.

Configuration procedure

1.

Configure Router A:
# Configure VRRP to operate in load balancing mode.

system-view

[RouterA] vrrp mode load-balance

# Create VRRP group 1 and configure its virtual IP address as 10.1.1.1.

[RouterA] interface ethernet 1/1

[RouterA-Ethernet1/1] ip address 10.1.1.2 24

[RouterA-Ethernet1/1] vrrp vrid 1 virtual-ip 10.1.1.1

# Set the priority of Router A in VRRP group 1 to 120, which is higher than that of Router B (110)
and that of Router C (100), so that Router A can become the master.

[RouterA-Ethernet1/1] vrrp vrid 1 priority 120

# Configure Router A to operate in preemptive mode so that it can become the master whenever

it works correctly. Configure the preemption delay as 5 seconds to avoid frequent status
switchover.

[RouterA-Ethernet1/1] vrrp vrid 1 preempt-mode timer delay 5

[RouterA-Ethernet1/1] quit

# Create track entry 1 to associate with the physical status of Ethernet 1/2 on Router A. When the

track entry becomes negative, it means that the interface fails.
