Well it's time to recertify the ol' ccnp and i've decided on the MPLS exam642-611. (given the new policy) my question is, I own the implementing mpls and vpn architectures volume 1. For this exam, is it necessary to study the volume 2 of this book? or will it just confuse more. I've browsed through it at the library and found it to be complicated, i've read 1 and feel pretty confident about it.. exam date is in 14days. And i was just wondering if the detailed Carrier's Carrier VPN and Multicast VPN, IPv4+labels crap was necessary, not to mention the full chapter on VPDN's and NAS servers etc..
plz let me know.
