Not very happy
on February 1, 2007
I read this book in preparation for my Cisco MPLS exam, on my way to becoming a CCIP. I bought the 2 volumes. After reading the first one, I decided not to go ahead with the second. I work for a giant service provider, which is a fortune 500 company as well. I specifically work at the core network level. The core network transitioning from legacy SDH towards a pure IP/MPLS solution meant for me a fundamental understanding of MPLS.
First of all, never throughout the book did I understand what exactly was the problem that MPLS was aimed at solving. The words are there and you will read them 3 or 4 times. But nothing will sink in.
Configuration examples are there alright, but there was no clear, separate explanation of each and every component of the architecture. When and where do we use MP-BGP, where do we redistribute which protocol, and so forth. You will have to do a lot of figuring out on your own, which will certainly mean a lot of guessing. And that is NOT why I bought a book on MPLS and VPNs :-)
This is not a book written in a style which assumes that you know nothing about the subject. On the contrary, it is so complicated that I think you need to know everything beforehand, and this book is only for reference ! This is certainly NOT a book for MPLS dummies (like myself).
The above conclusions I arrived at after I read one specific resource. Try to read the Cisco authorized course material, which is simply the instructor projector slides printed on paper, and a little explanation under it. Forget about the exam for a little while. For whoever is interested in REALLY understanding MPLS, and really understanding where each protocol goes, and the where and how and why of almost anything related to MPLS and VPNs, read that resource. Then compare it to this book. You will get my point.
