I had to augment the book information with other information, including another 640-604 book, web information, etc. before I felt comfortable with the covered material.
Anyone see anything wrong with this EIGRP calculation? Mistakes like this are all through this [cruddy]book. I put up with them all the way up to the EIGRP chapter when I was trying to understand the math behind the routing metrics. I have waisted 2 weeks of my time fighting through the mistakes in this book. Save yourself some headaches and do NOT buy this book. I will never by another Syngress book again. My better judgement against waisting money in any respect has kept me from thowing this book into the garbage. Maybe I can burn it in the fireplace this winter. It would make me feel better anyway. On to Cisco Press.
More disappointing was that the CD continued to have those same errors.
For example, it says that a PRIVATE address range was:
10.0.0.0 - 255.0.0.0
When the correct answer is:
10.0.0.0 - 10.255.255.255
Please do not buy this book! Unless you think its fun to constantly be checking with other sources to ensure what you are studying is correct.
I bought the book because I liked the way that it covered the exam topics and for the boatload of questions throughout the book. I don't know if the other books are any better, but with this one I find myself gathering information from other books and online sources to check what I'm reading. This is annoying if your trying to cover the information quickly.
The chapter on BGP was so confusing that I read the RFC instead !
I am now using Todd Lammle's Book instead, which is much better.
ANKUR RAWAT CCNA,CCDP, MCSE, MCSE+I,
When trying to contact the author and editor for comments, I was passed from one HR personnel to another before eventually giving up.
I've developed technical courseware books in the past and highly recommend not to buy this book if you are studying for the CCNP Routing exam. Other recommendations would be to read the Exam Cram and Cisco Press Routing books.
Additionally, the book seems to be missing pieces that were intended to be included. Review sections refer to topics having just been covered - that were never mentioned at all in the preceding material!
From this, it seems it was rushed into print in order to capture the market for the new Cisco 640-503 test, in what is a most cynical manner, because if the intent is to teach, not just make money, then it's a failure to give people who are buying the product false information.
Too bad. It's a good pre-publication rough draft suitable for editorial review, not for sale. In my opinion Adam Osborne ought to give purchasers a refund. Or be sentenced to re-typeset it personally, using his original Osborne-1 transportable CP/M-80 machine...
Let me explain why I took away 2 stars.
Firstly, this book misses 1 * for numerous of typos, syntax errors, and logic errors all around the book. These errors will slow your study time down.
- Typos: when you see inconsistent diagram or R1 and R2 mistakenly switched, you'll have to think twice and reread the whole paragraph again to fit all things together. You can find this kind of errors all over the place. I found out that they're really annoying! They're not 'normal' typos like 'advaned' instead of 'advanced' which can be corrected quite easily using any word processors.
- Syntax error: if you take all the command syntax for granted and sit for the exam, you'll be in trouble. Always double check with Cisco web site or actual router commands or even another chapter of the book. For example, one chapter tells you that the command to change EIGRP hello-interval is ip eigrp hello-interval, while another chapter tells you is ip hello-interval eigrp which is off the correct one.
- Logic error: this is the worst error of all! I couldn't believe my eyes the Advanced EIGRP chapter teached me that the best path for EIGRP is the one with the highest metric, while the previous chapter just explained quite clearly that is the lowest one. It seems that the author of this chapter doesn't even understand the basic concept of EIGRP!
Secondly, I took another 1/2 * for lack of 100% of coverage as advertised. Where are the bgp peer group and bgp community sections as stated by official curriculum from Cisco? The basic coverage of BGP is also shallow.
Lastly, I took another 1/2 * for:
- Bad ExamSim software not as promised. The ExamSim only contains 65 questions taken from the book and that's it! No pools of questions and the test engine is not as sophisticated as it's advertised!
- Inconsistent style of writing
- Lack of correct configuration mode for the commands explained, i.e. you don't know whether the command is for interface or router configuration mode
- Not providing summary of commands in the end of chapters.
It will make the readers' life easier if the editors did their jobs properly to eliminate typos and errors and to make the style of writing consistent throughout the book. Anyway, that's what they are paid for, right?
Now, the good news for the sake of fairness!
The overall coverage of the book (although not 100% as explained before) can help you pass the CCNP Routing (640-503) exam, if you read carefully and sceptic enough and given the pass mark of the exam is still 690. That's what the 3 * for. I hope the publisher can make the book better in the next edition.
Conclusion: My suggestion is to get a better book while you could, like Cisco Press' CCNP Routing Exam Certification Guide, which is the best book I've ever seen so far for the Routing exam (their test engine is superb!). If this book is your only choice, just take it. Be patient, and cross check. You still can pass the exam like I did!

The CDs sell book. The info can be gotten any number of places. But the CD helps in preparing for the multiple choice test.
This CD is bare bones. Many of the questions are direclty lifted from the end of chapter quizes. And the "exam sim" has only one mode - test mode of all the possible questions, with no "instant explanation" or links to more info.
Buy the book for the text, buyer beware of the CD.
In this 620 plus page book, that can be used in a classroom environment, start the road to certification with an introduction to switching and layers 2, 3 and 4 and then is continues with switch block concepts, this is the first book I know of to cover this topic.
The authors then explain VLAN and spanning tree protocols very well, they make every attempt to give you more than enough information. Also another first time topic is the Inter-Vlan.
You then go into multi-layer switching, HSRP, multi-casting, Diagnostics and remote management. As with other books from Osborne there is practice questions, exercises, lab questions and a self-test all this coupled with an abundance of diagrams, figures, router screen shots and tables.
Finally another Osborne standard is the cd, this one has over 200 questions and is put together with ExamSim and CertTrainer. The layout of this book is more that exam material it is material that can be used for later reference.
The author's start off the book with support resources, things like tools, analyzers, network monitors are covered. Then you move on to troubleshooting methods. The author has put together an excellent breakdown of the problem-solving model.
The best thing about the model is the fact that is can be used in all aspects of troubleshooting. The areas of troubleshooting that are covered in the book include Lans, WANS, troubleshooting tools, frame relay and ISDN.
Another plus for the book is that there is also non-hardware troubleshooting covered in topics like Routing protocols of RIP, OSPF, IGRP, EIRGP and BGP. IP and AppleTalk as well as IOS Commands and are given coverage.
For the first time I know there is coverage of VLANs with routing and switching troubleshooting covered. All this in 900 pages and coupled with the practice cd with over 200 questions and this might be one of the best values I have seen this year.
The authors start off with IP routing and addressing fundamentals which is the base of the foundation in routing. There is then 170 pages of coverage for OSPF, which tackles operation, configuration in the simple and multiple areas and WANS.
Then you'll move on to EIRGP in both the large and small networks followed up by BGP uses, messages, monitoring and scalability, which is detailed in 140-page breakdown. These two protocols are covered about the best I have seen so far.
While the book doesn't cover IGRP there is coverage of filtering, policies and mappings. There are exercises, self-tests and lab questions at the end of every chapter and tips and exam watch notes throughout the book making your studying a little easier.
The additional cd included comes with over 200 practice questions fro the exam 640-503. Also included is the software packages ExamSim and CertTrainer to round out a very complete package.
