VRRP Tracking Interface Configuration
Network requirements
Even when Switch A is still functioning, Switch B (with another link to connect with the outside) can
function as a gateway when the interface on Switch A and connecting to Internet does not function
properly. This can be implemented by enabling the VLAN interface tracking function.
The VRRP group ID is set to 1, with configurations of authorization key and timer.
