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