Qiong,

MAP could also create its tunnel endpoint address from the WAN prefix (not address).
so you'd have, for CPE tunnel end point address:

1) arbitrary IPv6 address (DS-lite)
2) WAN IPv6 address (DS-lite, LW46, Public 4over6)
3) Algorithmic End-user IPv6 prefix + Well known interface-id (MAP)

cheers,
Ole
