IPv6 Tunnel
Definitely depends on the requirements. I usually try to figure out if it’s point-to-point (ipv6ip) or multipoint (then I use isatap or auto6to4). If it’s between to routers than p2p tunnel is used. If they say “treat the IPv4 network like an NBMA cloud”, then p2mp. I think you can pretty much narrow it down to those two types…please let me know if I am mistaken.
