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.
