Regarding the "about the authors" specifically Kieran Milne it states
He is the author of the forthcoming book, Junos Networking Essentials (O’Reilly), and contributes to exam development for the Juniper Networks Technical Certification Program
But this book still not evident , so is there a planned date for this ?
Sorry for the delay in responding to you. I don't actually see that title as being in production, released, or canceled in our system. The only mention of it I see anywhere was on that author information page.
The only books we have on Junos can be found here:
Sorry I didn't have any more information on that for you.
