Total gap filler. Take theory learned in CCNA add real life and you have this book. If you work with Cisco gear and need a go-to refresher this is it. Great on the job every day book for network admins and engineers, also recommend for anyone who is thinking about CCNP. My new favorite networking book.

More advanced than others, so it's indicate to experienced professionals. If you like to discover special things about network, it's the goal.

This is the best book I've read this year (2009). It explains core principles of networking in such a way that everyone understands. I feel much more knowledgeable and confident in my networking ability now after reading this book.

This epically-titled O'Reilly book is a well-organized collection of network configuration tips, stories, and common "gotchas", as told by a self-admitted grouchy old network admin to younger, wet-behind-the-ears network administrators.
The author, in a move uncommon to most networking manuals, just cuts to the chase and says what needs to be said. Everything is told from a Cisco perspective, with Cisco terminology, and the only hint of variation allowed for is the occasional explanation when something is radically (or subtly, in some way that would ruin everything when you least expect it) different between CatOS and IOS. This is undeniably a good thing; it keeps the book short, and realistically, Cisco is one
of the forefront leaders in the enterprise network market.
A wide range of topics are talked about - possible problems that you could run into with auto-negotiation on your fast-ethernet network, how to configure spanning tree or etherchannel, getting QoS to work properly, and a whole host of topics one should know when creating one's own medium-to-large sized network. Even for those that already know how to implement these features, the author explains exactly when someone would want to use these features and how they evolved, and how they ought to be properly used.
I would recommend this book to anyone interested in enterprise
networking - ranging from the relatively professionally uninitiated like myself (I only do networking administration for Computer Science House at the Rochester Institute of Technology) to those who are just transitioning from networking classes to actual jobs, who will benefit perhaps the most from the book's tips and tricks from a person in industry, or even the average middle-aged network administrator, who may find a large portion of the book a snooze, but likely still pick up a trick or two that was previously unknown.

I like this book, but I found it was weak on the contents of routing, it seems that the author's knowledge limited for routing, the reader will be easily confused for this part. I recommend "routing tcp/ip" for routing.
