9780201657739: EIGRP for IP: Basic Operation and Configuration (The Addison-Wesley Networking Basics Series)

The Enhanced Interior Gateway Protocol (EIGRP) from Cisco Systems is one of the most widely used intra-domain routing protocols in todayis corporate networks. Although EIGRP is easily configured, the inner workings are generally not well understood. The result: nonoptimized networks that lead to chronic and costly problems requiring time and energy to solve. EIGRP for IP is a concise, complete, and practical guide to understanding and working with EIGRP. It focuses on EIGRP in the context of IP, although the principles learned from this guide can be applied to the other major network protocols that EIGRP supports, including IPX and AppleTalk. The book provides an overview of essential concepts, terminology, and EIGRP mechanisms, in addition to a look at the most important configuration options. It examines network design with regard to EIGRPis capabilities, offering concrete tips for specific design issues that arise in EIGRP networks. Also featured is an experience-based guide to EIGRP troubleshooting, with solutions to many commonly encountered problems. Specific topics covered include: The foundations of EIGRP, including the Diffusing Update Algorithm (DUAL) A comparison of EIGRP to other interior gateway routing protocols Configuring summarization Standard and extended access distribution lists Hierarchy and redundancy in network topology Path selection Multiple EIGRP autonomous systems Isolating misbehaving routers Solving problems with neighbor relationships Stuck in Active (SIA) routes Serving as both a complete reference and a practical handbook, EIGRP for IP is an essential resource for network professionals charged with maintaining an efficient, smoothly functioning network.

Excerpt. Reprinted by permission. All rights reserved.:

Preface Cisco Systems designed EIGRP (Enhanced Interior Gateway Routing Protocol) as a routing protocol to support the Internet Protocol (IP), Novell's IPX, and Apple's AppleTalk protocols. EIGRP is used in networks of all sizes, including many large corporate networks, across the world. Routers direct traffic-user data in the form of packets-through the network toward its destination. Routing protocols provide the road signs for the routers to use to decide where to forward the traffic to next on the path to the destination.

EIGRP is designed to provide routing knowledge within a single domain-or between routers controlled and maintained by the same group of people. A domain is usually understood as containing all the routers owned and operated by a single administration, such as a company or a department.

Although EIGRP can provide routing information for various protocols, we have limited the scope of this book to just IP. The primary reason for this decision is to maintain focus and clarity. Most of the theory and the design principles you learn here can be applied to networks using EIGRP to route protocols other than IP.

This book has been designed to provide a quick but complete description of EIGRP and its use. Throughout our experience, working firsthand on the design and troubleshooting of EIGRP networks, we have found that the protocol is typically not well understood or documented. Although EIGRP is very easy to configure, the lack of educational resources explaining how EIGRP functions has led to nonoptimized networks and has caused issues to chronically pop up in many of them. Our intent is to partially fill the documentation gap with this guide while also providing design and troubleshooting guidelines to the most common scenarios and problems. The intended audience includes people with some networking experience and at least a basic understanding of routing protocols.

Chapter 1 begins with EIGRP theory, explaining the basic concepts, terminology, and mechanisms EIGRP uses to provide routing information. Chapter 2 takes a brief look at the most important configuration options with EIGRP. Chapter 3 considers network design principles within the framework of EIGRP's capabilities and includes tips on basic network architecture and specific studies on situations you may find in an EIGRP network. Finally, Chapter 4 provides information on troubleshooting various conditions you may find within a network running EIGRP. Problems ranging from errors building neighbor relationships to troubleshooting Stuck in Active (SIA) routes are covered in this chapter.
