Summary: Excellent Book..!!!
Review: This is an excellent book and I can't wait for the 2nd coming..!! This book is a must have for anyone who works with Cisco equipment, it's great for the CCIE Lab as well as the CCIE Written test. If the 2nd book is anywhere near as informative as this book then I'll own it too. Very well written book and very detailed, the author did a wonderful job of keeping you interested and not making you feel like an idiot, which alot of Cisco books do these days. I would recommend this book to anyone..!!

Summary: One of the BEST books on routing
Review: This is one of the best books on routing. Check the errata list on cisco's web site though.This book is on par with Cisco LAN Switching by Kennedy/Clark, Tanenbaum's Computer Networks, and Comer's book. Simply one of the best books to come off the Cisco Press! hsb

Summary: A Must-Read!
Review: This is one of the most comprehensive books on IP routing anywhere. Jeff Doyle does an excellent job in describing the various internal routing protocols, e.g. OSPF. Each chapter is well documented and concise. A must-read for both the networking tenderfoot and the seasoned professional.

Summary: This book is definitely a must buy!
Review: This is the best book I've read on IGP Routing Protocols and their implementation on Cisco Routers. The book takes a reader from basic IP routing fundamentals through to in-depth implementation of the most complex IGP routing protocols. The book is easy to read and flows in very logical manner. I especially enjoyed the chapter (8) on Cisco's EIGRP; It was the most detailed coverage I have read on Cisco's proprietary Interior routing protocol. Additional Comments: I did note the following errors in the books print listed by chapter: Chapter 5 Page 193, Paragraph 1, Sentence 4 and 5 The statement with regard to holddown timers and Routers running RIP routers is false. The statement read "If an advertised hop count is higher than the recorded hop count and the update was received was originated by the recorded next-hop router, the route will be marked as unreachable for a specified holddown period. If at the end of that time the same neighbor is still advertising the higher hop count, the new metric will be accepted". The reason this is wrong is because, a router that receives a route with a higher metric than the currently recorded metric and the advertising router is also the recorded next-hop router, the router will immediately install the new metric. (lab tested). Appendix F Page 970, Chapter 7, Answer 1 The given answer is not completely correct as stated. First the answer states that the router labeled C on page 321 and who's configuration is on page 324 will interpret the RIPv2 routes 192.168.90.0/29 and 192.168.13.86/28 coming from routers A and B respectfully as 192.168.13.64/27 and discards them because this route is directly connected to one of router C's interfaces. This is incorrect first because the routes that will be advertised by routers A and B will be 192.168.13.80/29 and 192.168.13.80/28 respectfully not 192.168.13.86/28 and 192.168.90.0/29. Secondly because router C is configured with the default rip settings, which allows the router to advertise RIPv1 and receive RIPv1 and RIPv2, which will allow router C to correctly interpret the masks sent with the RIPv2 updates sent by routers A and B as such router C will have both (Lab Tested). Appendix C, Chapter 11, Answer 1 The answer as stated is not completely correct. The answer states that in order to redistribute between the IGP domain and the RIPv1 domain the router labeled B should have its mask changed from /27 to /28. Although this facilitates the routes from the IGRP domain into the RIPv1 domain it does not completely facilitate the reverse. The reason for this is that when router B receives the RIPv1 updates from router C it interprets those routes to have a /28 mask due to the new mask on its E1 interface. This results in the IGRP domain believing that the subnets in the RIPv1 domain have only 14 hosts per subnet where as they really can have as may as 30 hosts. In example take the subnet 172.16.2.32/27 which possibly contains hosts 172.16.2.33 -62 in the RIP domain, when this route is redistributed into the IGRP domain it would be interpreted to only contain hosts 172.16.2.33-46. This would cause packets originating in the IGRP domain destined for the hosts numbered 172.16.2.47-62 to be returned unreachable by the routers in the IGRP domain without further configuration. i.e. static routes.

Summary: This book is the HOLY man's BIBLE..You must GET it...!
Review: What this book did for me was strengthen my knowledge and understanding about network routing protocols. I've been searching for a book such as this one, with such detailed information about routing metrics, EIGRP DUAL, OSPF/RIP router redistribution, etc... Now when I go on interviews, I'm more confident than every before. There are a certain number of books that I call the BIBLE which means never go to work without them,(#1-Doug Comer TCP/IP Volume-1, #2-Mark Miller Troubleshooting TCP/IP, #3-Kennedy Clark & kevin Hamilton Cisco Lan Switching,) just to name a few, and now added to that list is Jeff Doyle's Routing TCP/IP Volume-1. What is Jeff Doyles email address, the one listed does not work.

Summary: Excellent starting point
Review: When it came down to researching routing protocols for some training courses the company I work for is developing, Jeff Doyle provided the perfect starting point. In this book, he uses simple language (well, as simple as the computer world can be) and clear-cut definitions that won't leave your mind spinning. Read this book before you read any other material related to routing protocols (including the RFCs). Once you've read it, you will be able to sift through the disorganized information found in most technical books and (especially) in the RFCs. You may not even necessarily need to read any other supplementary material (Doyle is thorough in his analysis of each routing protocol). Although it is a cliche' statement - I highly recommend this book.
