# Configure the VFs to monitor track entry 1, 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.

After the configuration, Host A can ping external networks successfully. To verify your
configuration, use the display vrrp ipv6 verbose command.
