CiscoPress released last month the updated CCIE R&S Official Cert Guide, for the v5 blueprint. After two lab attempts, I thought it would be a good idea to refresh on reading a bit and give it a cold start.
I am still reading the EIGRP chapter and boy, the book is great. The previous v4 book (not written by Narbik) was, in my opinion, a large topic list, as if the author simply decided to peruse the old blueprint and write a few paragraphs about each topic.
In this book Narbik (and co-author Peter Paluch) decided to take a different turn and give readers the inner workings of the topics. Was it exhaustively explained in other books (CCNP and so)? Yes. But not the same way and not the same depth. It sincerely feels like the authors know that for example, EIGRP's FD is very commonly misunderstood. And they go down the guts to make it clear. It is very refreshing (and I admit I misunderstood FD). The text is dense sometimes, but it is welcome.
Only the first volume has been released as of writing this post. It is a great book for any R&S professional. As I always like to say, the key to study for certifications is studying only the necessary, so if you are studying for CCNA/CCNP, just don't go that deep yet, keep it simpler while you can. But if you already work with it, the information in this book is highly useful.
