Sorry Cisco I love your stuff but this book falls well below the standard I would expect from one of your publications. I'm a CCIE I passed my lab Jan 2001 and took my recertification 2 years ago in IP routing. My job has changed a little since then and I no longer have as much routing exposure as I used too I'm now all LAN at a large datacenter and some OSPF. Anyway I got this book to help me with my second recert, I wanted a quick read it once and pass it guide. Well with the CCIE its just not possible, sorry but its simply not that type of certification not even the written you need to know this stuff DEEP, no shortcuts IMHO.This book promises a lot but simply does not live up to it, as a CCIE I used this book to take my recert and failed. So I hit the real books, the one's that got me through the exam and lab 6 years ago, TCP/IP Volume 1 and now Volume 2 by Jeff Doyle, Lan switching for CCIE's, and Internet routing architectures from Halibi (BGP is also covered in the Doyle V2 book now), and passed the written exam with a 93%. I would also add a Cisco specific QoS book to the reading list as well for the 350-001 exam as there was a lot of QoS in the exam and Doyle does not cover it. The titles above brought a lot stuff flooding back to me, stuff I forgot and stuff that the certification guides like this one were not able to restore from my memory.Believe me there are no shortcuts to getting this I should know it cost me over $300 for the exam and 160 bucks on 2 certification books to find that out, oh yeah this also applies to the flash card book for the CCIE written also available from Cisco. Positives are that the book does have a good general coverage of the subjects for day to day referance but no where near deep enougth and links to websites with the rest of the info you need but with this book and the flashcard book alone your not going to pass this the written exam. Its way to deep an exam for that save your money and get the Doyle books.
