1.4.2 VRRP Tracking Interface Configuration

I. 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 backup group ID is set to 1, with configurations of authorization key and
timer.
