Multiple VRRP Group Configuration Example
Network requirements
z
Hosts in VLAN 2 use 202.38.160.100/25 as their default gateway and hosts in VLAN 3 use
202.38.160.200/25 as their default gateway.
z
Switch A and Switch B belong to both VRRP group 1 and VRRP group 2. The virtual IP address of
VRRP group 1 is 202.38.160.100/25, and that of VRRP group 2 is 202.38.160.200/25.
z
In VRRP group 1, Switch A has a higher priority than Switch B. In VRRP group 2, Switch B has a
higher priority than Switch A. In this case, hosts in VLAN 2 and VLAN 3 can communicate with the
