[j-nsp] Study books.

[Keith]

Hi.

We just purchased an MX480 to replace our aging 7206vxr-G1.

We spent a few months going back and forth, C or J. In the end J worked 
harder
for our business and ended up with a redundant MX480.

Our only experience was with an M10i five years ago so we are green.

My coworker and I need some new books. Looking at Amazon, most of
the books are at least five years old. Are any of them still relevant 
enough to
warrant purchasing them?

Anyone have books they want to recommend?

Thanks,
Keith
