Virtual LAN Overview

A Local Area Network (LAN) is a collection of devices in the same broadcast domain. As a network

increases in size, segmenting a single broadcast domain into multiple domains improves scalability,

manageability, and security. However, doing so using physically with separate switches and routers is both

static and expensive.
