Chapter 3. EIGRP Network Design

The previous two chapters described many of the important network design techniques used to meet the design goals of high resiliency, manageability, and scalability. Now it is time to put these techniques into practice using the Cisco advanced distance vector routing protocol, Enhanced Interior Gateway Routing Protocol (EIGRP). These techniques will be applied to the networks shown in Figure 3-1.
