IS-IS reference

I was wondering if I could talk with someone who has recently implemented IS-IS. I'm attempting to move a small NSP away from static routing and based on their topology - OSPF would have to be configured all in Area 0. Since the technology provided by this NSP to their customers will include multicast services (video specifically), I thought that I should consider IS-IS while the slate is relatively clean. If there is someone who has implemented this routing on their network that I could ask a few questions of (practical experience), I would appreciate it. Jack Crowder monterey@spies.com
