there is nothing intrinsic in a 1280 MTU or a dynamic prefix with 6rd.
that's if so a deployment choice. you can very well get a dynamic prefix with "native IPv6"
in the access network too.

6rd offers native IPv6 on the LAN side.

as an end user, why would you care how the traffic was carried in the network?
is PPPoE over L2TP "native"? is anything over an MPLS tunnel native? ;-)

cheers,
Ole
