# Enable Router C to send RA messages, so that hosts in network segment 1::/64 can learn the
default gateway address.

# Create track entry 1 to associate with the physical status of Ethernet 1/2 on Router C. When the
track entry becomes negative, it means that the interface fails.
[RouterC] track 1 interface ethernet 1/2
# Configure VF tracking to monitor track entry 1 and specify the value by which the weight
decreases, making the weight of Router C 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.

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