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 your environment already has an existing combination of bridges and routers within the network, this chapter shows how you can scale your campus intranet to meet the ever-increasing demands of your business. In this chapter, you will learn about a new approach to campus networking called multilayer switching. This chapter discusses the correct placement of Layer 2, Layer 3 and multilayer devices on a campus network.

Finally, this chapter 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.
