A book of quality rather than quantity. This book contains some interesting information on Cisco router processes and internal packet flows. However, in the main the majority of information, excluding the GSR and CEF overviews, have been presented before at Cisco Networker/CCIE seminars. I was hoping for more detail, which unfortunately the book was lacking. i.e. The book does not really detail how to performance tune a Cisco router, and the more importantly the functionality of the various processes. Admittedly, one can guess what various processes do, but it is disappointing when text has always been available for UNIX and other operating systems. To me this book does not provide access to new (previously un-disclosed) information.
In saying all of this, the book is still a great piece of reference material.

This book provides an excellent description of the intrinsics of Cisco IOS, the various router platforms, and IOS switching methods.
The same information could probably be gathered from numerous Networkers presentations and similar, but here you've got it all.
The final chapter on QoS seems kinda misplaced, and not up to the same standards as the rest of the book.
I wish they'd make a similar book on the Catalyst switches.
