ZyWALL USG 1000 User’s Guide

A Virtual Local Area Network (VLAN) divides a physical network into multiple 
logical networks. The standard is defined in IEEE 802.1q.

Figure 257   Example: Before VLAN

In this example, there are two physical networks and three departments A, B, and 
C. The physical networks are connected to hubs, and the hubs are connected to 
the router.

Alternatively, you can divide the physical networks into three VLANs.
