Inter VLAN Group Routing:
In Port-based tagging, the administrator can specify member hosts of one VLAN group to be able or not able
to communicate with another VLAN group. This is a communication pair, and one VLAN group can join many
communication pairs. But communication pairs do not have a transitive property. That is, if A can
communicate with B, and B can communicate with C, it doesn’t imply that A can communicate with C. An
example is shown in the following diagram. VLAN groups of VID 1 and 2 can access each other but the ones
between VID 1 and VID 3 and between VID 2 and VID 3 cannot.
