Negative Positive
Title: Good enough reference...
Review: And not much else. The author tries to pack too much info into a single book. It did work for Lammle for the CCNA study guide. However, CCNP covers a lot more. For a recap of technologies this book is fine. If you are looking for a deeper coverage of routing protocols however, check out "Cisco IOS for IP Routing" by Andrew Colton (ISBN 0972286209). That book explains the mechanics of modern routing protocols, such as RIP, EIGRP, OSPF, IS-IS, and BGP in great detail.
