This means if a station moves from VLAN 1 to VLAN 2, it receives broadcast message sent to VLAN 2,but no longer receives broadcast message sent to VLAN 1.
It is obvious that the problem in our previous example can easily be solved by using VLANs. Moving engineers from one group to another through software is easier than changing the configuration of the physical network. VLAN technology even allows the grouping of stations connected to different switches in a VLAN. Figure 15.17 shows a backbone local area network with two switches and three VLANs. Stations from switches A and B belong to each VLAN.
