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 has not the transitive property. That is, A can communicate with B,
and B can communicate with C, that doesn’t mean A can communicate with C. An
example is shown at following diagram. VLAN groups of VID is 1 and 3 can access
each other but the ones between VID 3 and VID 4 and between VID 1 and VID 4
can’t.
3.1.2.2.2 Port-Based VLAN
A port-based VLAN is a group of ports on an Ethernet switch or router that form a
logical Ethernet segment. There are four LAN ports and up to eight virtual APs in this
device, so you can have various VLAN configurations to organization the available
LAN ports and virtual APs if required.
