1.1.2 IEEE 802.1Q VLAN Application Example
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into
multiple logical networks. Stations on a logical network belong to one group. A station can
belong to more than one group. With VLAN, a station cannot directly talk to or hear from
stations that are not in the same group(s) unless such traffic first goes through a router.
