InterVLAN routing

Devices within a VLAN can communicate with each other without the need of Layer 3 routing. But devices in separate VLANs require a Layer 3 routing device to communicate with one another.

To allow hosts in different VLANs communicate with each other, we need a Layer 3 device (like a router).

The routing traffic from one VLAN to another VLAN is called InterVLAN routing.
