I don't get why Juniper and Cisco trie-lookup forwarding would differ in comparing IPv4 and IPv6; Juniper does a 8+1+1+1+1+... search until a leaf node is found, while Cisco does 16+8+8 (or something near it but still with 3 phases); for both architetures, IPv6 longer addresses implies walking more deeply into the tree in order to find where to route.
ahhh. you have been watching marketing architecture presentations. otoh, we have been using real routers. randy
