Figure 51   Network diagram for VRRP

 

Switch A is the master and Switch B is the backup in a VRRP group. Both Switch A 
and Switch B have an interface connected with the Internet. Configure the VRRP 
interface tracking function, so that when the interface connected with the 
Internet on Switch A becomes unavailable, Switch B can replace Switch A to act as 
the gateway even if Switch A is still working.

Set the group number to 1.
