| Overview

As corporate intranets continue to evolve, network managers and architects are faced with a multitude of options in building and modifying their networks. Starting from a premise that the existing environment already has a combination of bridges and routers within the network, this module shows how to scale the campus intranet to meet the ever-increasing demands of the business. In this module, the student will learn about a new approach to campus networking called multilayer switching. This module discusses the correct placement of Layer 2, Layer 3, and multilayer devices on a campus network.

This module also describes a set of building blocks, which presents a logical design for the network irrespective of any product that may be implemented. The success of any campus intranet is based upon the placement of network services that, when applied correctly, will guarantee continued scalability.

Finally, this module describes the command-line interface (CLI) on Cisco switches, including aspects such as command-line recall, command editing, uploading and downloading code images, and configuration files.
