Virtual LANs (VLANs) offer a method of dividing one physical network into multiple network; in other words VLAN divides single broadcast domain into multiple broadcast domains. However, VLAN-enabled switches cannot, by themselves, forward traffic across VLAN boundaries. For inter-VLAN communication, a Layer 3 router is required (Dell, 2004). In this paper we discuss the VLAN protocol and provides step-by-step commands for configuring VLAN routing using the Cisco 2950 switches, we will also demonstrate creation of VLAN and Inter-VLANs communication with the help of Packet Tracer 5.2. (For free download www.packet-tracer.com/) With the help of this paper, Network administrator can increase performance of network, improve manageability of network and increase security options.
