Query: Man, am I glad I bought this book!

With Cisco changing the CCNP requirements from the Routing exam to this exam, this book is just what I needed! Thank you Cisco for doing this and then having this book avialable to study for the exam. Whew!The new BSCI exam is basically the same as the old routing exam except they have IS-IS on the exam. This book has everything you need to pass the new BSCI exam and fill your CCNP requirements.
