If you are using Cisco routers in your network and are in charge of administration then you will want to have this book readily available. Not just a book about troubleshooting, the introductory portion provides a strong education in the Cisco hierarchal approach, the layered troubleshooting approach, and the problem resolution model approach.
This is followed by a solid explanation of protocol behavior and characteristics. Chapter three starts the actual diagnostic mechanisms and Cisco TCP/IP commands. Chapter four then covers diagnostic tools including network monitors, simulation tools, and Cisco IOS diagnostics. The next several chapters involve troubleshooting the actual protocols including TCP/IP, IGRP, EIGRP, OSPF, IS-IS, and BGP. The final chapter involves troubleshooting in a redistribution routing environment.
Some of the strongest reasons for recommending this book include the realistic scenarios for every size network, the straight-forward and efficient troubleshooting methodology proposed, and the thoroughness of the material. The text covers all the essential material tested in the Cisco exam Internet Troubleshooting Support.
Loaded with illustrations so you can visualize what is happening and understand the concepts easily, this is an excellent book for anyone working with Cisco routers. The included CD contains a study program with multiple-choice questions to test your knowledge, the source code for all code in the book, all the tables and illustrations in the book. The index is a little skimpy for a book of this size and type, but even with that shortcoming Cisco IP Routing Protocols is a highly recommended purchase and one of the best books available for anyone working in a Cisco environment.
