The complete guide to IP routing for all network professionals
Four routing protocols-RIP, OSPF, BGP, and the Cisco protocols-are at the heart of IP-based internetworking and the Internet itself. In this comprehensive guide, respected telecommunications consultant Uyless Black teaches network professionals the basics of how to build and manage networks with these protocols. Beginning with an exceptionally helpful tutorial on the fundamentals of route discovery, architecture, and operations, Black presents in-depth coverage of these topics and more:
From start to finish, IP Routing Protocols focuses on the techniques needed to build large, scalable IP networks with maximum performance and robustness. Whether you're a service provider or an enterprise networking professional, here's the lucid, succinct guide to IP routing protocols you've been searching for.

This book is one in a series of books called, "Emerging Communications Technologies." As the name of the book implies, the focus is on how routes are discovered and used in the Internet.
The subject matter of this book is vast and my approach is to provide a system view of the topic. In consonance with the intent of this series, this general survey also has considerable detail but not to the level of detail needed to design a routing protocol, or to configure a bridge or router. For that, I leave you to your project team and the various specifications that establish the standards for routing operations.
This book is considered to be at an intermediate-to-advanced level. As such, it assumes the reader has a background in data communications.
I hope you find this book a valuable addition to your library.Use of Appendices
The subject of internetworking and route discovery is built on many concepts, and several supporting IEEE, ISO, and Internet protocols and standards. For those readers that are familiar with these subjects, I have not encumbered the main body of the book with a description of these systems. From previous experience, I also know that a substantial number of my readers will not have full knowledge of some (perhaps all) of these supporting and underlying operations. I also know that some of the readers are well-versed in these underlying, supporting protocols.
I have provided several tutorials on these subjects and have included them in the appendices to this book. I suggest you take a look at the appendices before you start reading the book, and then study those topics in which you need more information. On occasion, I will refer to an appendix to alert you to some required background information for a subject under discussion. If appropriate, I will refer you directly to a figure or a table to enable you to do a quick check to determine if you should divert to the specific material in the appendix before proceeding further.
With this approach, I hope meet the needs of readers with various levels of experience and knowledge.
