Campus networks

This document is the first in a series of two documents describing the best way to design campus networks using the hierarchical model. The second document, High Availability Campus Recovery Analysis, provides extensive test results showing the convergence times for the different topologies described in this document, and is available at the following website:

This document provides design guidance for implementing a routed (Layer 3 switched) access layer using EIGRP or OSPF as the campus routing protocol. It is an accompaniment to the hierarchical campus design guides, Designing a Campus Network for High Availability and High Availability Campus Recovery Analysis, and includes the following sections

For campus networks, Cisco recommends a hierarchical network design that distributes networking function at each layer through a layered organization. The hierarchical model enables the design of a modular topology using “building blocks” that are scalable and allow the network to meet evolving business needs. The hierarchical model is based on a modular design, which is easy to scale, understand, and troubleshoot because it follows a deterministic traffic pattern. The principle advantages of the hierarchical model are:...

As of November 8, 2010, Manually entered IP addresses are no longer supported on campus if the device is capable of using DHCP. This is true for normal dynamically assigned IP's and Static IP's. All NEW devices added to the network must be set to receive their network address via DHCP (Dynamic Host Configuration Protocol). This is the default setting for campus PC and Mac workstations and most printers. No user action is anticipated. There is no change or downtime expected for the vast majority of campus workstations or devices. We have made great efforts to put exceptions in place...

A campus network is a building or group of buildings that connects to one network, called an enterprise network. Typically, one company owns the entire network, including the wiring between buildings. This local area network (LAN) typically uses Ethernet, Token Ring, Fiber Distributed Data Interface (FDDI), or Asynchronous Transfer Mode (ATM) technologies. The main challenge for network administrators is to make the campus network run efficiently and effectively. To do this, they must understand current campus networks as well as the new emerging campus networks....

Both small and large enterprise campuses require a highly available and secure, intelligent network infrastructure to support business solutions such as voice, video, wireless, and mission-critical data applications. To provide such a reliable network infrastructure, the overall system of components that make up the campus must minimize disruptions caused by component failures.

This network documentation policy is an internal IT policy and defines the requirements for network documentation. This policy defines the level of network documentation required such as documentation of which switch ports connect to what rooms and computers. It defines who will have access to read network documentation and who will have access to change it. It also defines who will be notified when changes are made to the network.

The following 3 questions all refer to the scenario below: The company Certkiller manufactures and imports fasteners like bolts and nuts. The company's network consists of a main campus composed of three separate building that are less than 150 meters apart, connected with Category 5e copper wiring. Network access as well as distribution takes place by means of 100 Mbps hubs, and the core is a 100 Mbps Layer-2 switch. The company has been in existence for 8 years and thus development in the network resulted in a series of steps that involved minimal planning.
