In this article, I'm going to walk you through setting up a network with three VLANs, each using different subnets, and configuring a Layer 3 switch to route between those subnets. I was just wondering how to setup hosts for internet access in a layer 3 intervlan routing environment. How would I get the sales and accounts PC's on the internet. A point to note is that to provide an IP Address to a switch interface, the switch first must be a Multilayer Switch and all ports of an MLS is layer 2 by default. A Layer 3 switch can perform IP routing tasks as well as Layer 2 tasks such as VLANs. Moreover, a Layer 3 switch can typically route faster than a router, improving network performance.
