Query: Great book and an excellent reference too

I initially bought it to use for the CCIE R/S written to recert my CCNP/DP but went the two test route instead. However, I actually used this book to prepare for the BSCI, for the BSCI book was not that good. Though having many years experience with cisco networking and cisco press books I found that this book has enough of those "little specific" details that make it an excellent on the job reference.The wirless section is not bad too but if you already have a CWNA, CWSP and CWAP then you can probably skip it.Use Doyle's I and II for the foundation and this book for review and on site reference. Worth every penny.HTH
