Speaking as a router vendor, the possibly-mistaken-impression is so not the way IPv6 high-end routers silicon works when the router uses a TCAM. Sorry, I cannot provide any more details on our router implementation, but I can assure this audience that Thomas' belief is correct that IPv6 routing continues to be based on CIDR.
