There are four companies in the same building. They share the broadband network and use the
Vigor3300V router to achieve the load balance, security, and VoIP features. In this case, we
can define four VLANs including VLAN5, VLAN6, VLAN7 and VLAN8. The subnet of
VLAN5 is 192.168.1.0; the subnet of VLAN6 is 192.168.2.0; the subnet of VLAN7 is
192.168.3.0; and the subnet of VLAN8 is 192.168.4.0.
