Part 1 is written a relatively clear and concise fashion, and makes a good follow up or addition to a CCDP course of study. Part 2 is slightly rich with errors, and a bit more grab-bag like in its approach to the subject matter. Weighing in at around 250 pages of core material, this book is one of the lighter reads in the CCIE study course, and could be tackled by a less experienced candidate as well. On the whole a good book, but not a great one, I still consider it recommendable.
