content: This book is way over-priced for the level of information it offers. Just from browsing through the lab scenarios, I've seen plenty of typos, errors, and misconfigurations. And worse the scenarios are so basic, it makes you wonder how they can get it wrong. As a CCIE, I don't think these simple labs will help at all for the real exam. If these guys would have concentrated on the book instead if writting about themselves and congratulating one another, this book would have been much better.
