EXAMPLE 3
This final example illustrates the use of a 1D Trunk to connect a device to
a network of 802.1Q VLAN switches.
In this example, illustrated in Figure 4-7, a merger has taken place
between Redco and Blue Industries, the companies in the previous
example. The two companies have become divisions within a single
corporation, Green, Inc. A third group of stations, the Green, Inc. staff, is
added to the facility. Also, the Green, Inc. Network Administrators add a
Mail Server to the network on the first floor.
