I've been looking through the certifications, and from what I can see on the net, JNCIA-ER seemed to be very focussed on the product line as opposed to technical details. Hence, I decided to take the JNCIS-M (after thinking that the JNCIA-M would be too easy) and failed it.

Not because there's no P section, or that the L2/L3 VPN/Services don't play such a big role, but because I feel that I'm best equipped with this fantastic O'Reilly book, and I'd really like to give it a good going over! Thanks all for your advice, here's hoping I pass the JNCIS-ER when I get around to it!
