What is Inter-VLAN RoutingWhat is Inter-VLAN Routing? Each VLAN is a unique broadcast domain. Computers on separate VLANs are, by default, not able to communicate. Each VLAN is a unique IP subnetwork. To allow VLANs to communicate, we need a router to communicate among separate broadcast domains and unique IP subnetworks. Inter-VLAN routing, then, is a process of forwarding traffic from one VLAN to another VLAN using a router. | Chapter 6 Inter-VLAN Routing Inter-VLAN Routing Introducing Inter-VLAN Routing What is Inter-VLAN Routing?

Introducing Inter-VLAN Routing VLAN Tagged (10) Tag removed Traditional Inter-VLAN Routing: Traditional routing requires routers to have multiple physical interfaces to facilitate inter-VLAN routing. Each interface is also configured with an IP address for the subnet associated with the particular VLAN that it is connected to. In this configuration, network devices can use the router as a gateway to access the devices connected to the other VLANs.
