Just finished reading the book. Very well written and covers a lot of ground. Clear and to real life related examples which also illustrate very detailed interoperability issues with Cisco environment.
I am Juniper Networks Certified Instructor for M/T, J, EX, ES and I must say I wish the training material was written this way. This book could easily be used as a Student Guide on an EX-Series training.
I would recommend this book to anyone working with Juniper Networks EX-Series switches.
I bought this because Juniper wanted an additional £50 for printed documentation in a JunOS course I attended recently, which frankly is a bit of a cheek, and this had everything that the course documentation seemed to have, and more.
It provides some excellent resources on the EX platform, and in particular stacking and unstacking, which can be a bit of a nightmare.
