First of all, create two VLAN in the switch and named VLAN A and VLAN B with the following command. Download the Packet Tracer Inter-VLAN routing Lab for CCNA or create your own Lab.ġ. Let’s configure it on the below Inter-VLAN routing Lab. Configure Inter VLAN Routing How to Create VLAN on Cisco Switches? You can set IP address for each sub-Interface in order to route between VLANs.

In Inter-VLAN the physical Fast Ethernet interface of the router is divided into sub-Interfaces for each VLAN. The router you are using for Inter-VLAN routing must be compatible and support Inter-Switch Link (ISL) which is a Cisco Systems proprietary protocol, and IEEE 802.1q frame format for routing on the Fast Ethernet interfaces. Here we completely demonstrate the Inter-VLAN configuration using a Cisco router and a layer 3 switch. So if you want your VLANs hosts can communicate with each other, you must configure inter-VLAN routing using a router or a layer 3 switch. It means only hosts that are members of the same VLAN can communicate with each other. Basically, on a VLAN, no host can communicate with hosts within other VLANs. A step by step guide to configure Inter-VLAN Routing on the Cisco router or layer 3 switches.
