default gateway address.

# Create track entry 1 to associate with the physical status of VLAN-interface 3 on Switch B. When
the track entry becomes negative, it means that the interface fails.
[SwitchB] track 1 interface vlan-interface 3
# Configure VF tracking to monitor track entry 1 and specify the value by which the weight
decreases, making the weight of Switch B decrease by more than 245 (250 in this example) when
track entry 1 turns to negative. In such a case, another router with a higher weight can take over.

Verify the configuration:
4.
After the configuration, Host A can ping the external network. To verify the configuration, use the
display ipv6 vrrp verbose command.
# Display the detailed information about VRRP group 1 on Switch A.
