CCNP: Building Cisco Multilayer Switched Networks Study Guide: Exam 642-811 [With CDROM]

This is the second book from the Sybex Cisco Certification series I have purchased (after Todd Lammle's excellent CCNA book), and I was equally impressed with this work.The layout was up to the standard I expected, and I found the text flowed along nicely with sound explanations that were easy to understand. Some of the labs use CatOS-based switches, and I am told that Cisco is removing these from the exam, but they were useful to me as we still have some in our network. I particularly liked the chapters on QoS and switch operation, which I thought were covered in good detail, and I found studying from this book to be a rewarding experience, both in exam success and educational terms. Based on the quality of this book I shall be buying more from the same series when I prepare for the next exams in the CCNP certification.
