4.4.1Solving the Problem
Much of the existing network configuration can remain as it was for Example 3, 1D Trunk Connection to 802.1Q VLAN Network. However, Switch 3, Switch 5, and the devices that will make up Publication’s Grey VLAN have been added.
Switch 5 will be configured to isolate all AppleTalk protocol frame traffic to the devices in the Grey VLAN and all other protocol traffic to the Yellow VLAN. Switch 3 will link the traffic from Switch 5 to the buildings network backbone.
