This document is the first part of an overall systems design guide that addresses enterprise campus architectures using the latest advanced services technologies from Cisco and is based on best-practice design principles that have been tested in an enterprise systems environment. It introduces the key architectural components and services that are necessary to deploy a highly available, secure, and service-rich campus network. It also defines a reference design framework that provides the context for each of the specific design chapters helping the network engineer understand how specific design topics fit into the overall architecture.
