Today network engineers are employing more and more multilayer switched networks. These networks have the advantage of high throughput level 2 switching while retaining the level 3 routing functionality. The secret to the high performance of these networks is the hierarchical design model employing 3 layers Core, Distribution, and Access. This coupled with the advent of VLAN which breaks up collision domains has made the multilayer switched networks the design of choice.
