Summary and Info
This book is so full of errors that it is unacceptable. Save your time and money and wait for the second edition. If you MUST have it now, there are corrections available at Cisco Press. Be prepared, there are 5 sections to download and total over 50 pages. You will spend well over 40 hours just correcting the book BEFORE you can start reading it. There are way too many errors to read it first.
This might not be so bad but there are still errors in the book that do not get corrected and there are even errors in the corrections!!
I am a working Network Engineer and have passed multiple Cisco certifications. This has been the worst book I have seen from them. Even at their best you really need a book from someone else to get all the information you need.
