In your previous mail you wrote: Are you saying that if we use a bi-directional tunneling, the off-site MN can comunicate with the CN that is in the home-site of the MN? => exactly, this works as soon as the IPv6 stack supports multi-site as it should.
If so, I disagree. Consider the following condition. site A (fec0:0:0:100::/64): a home site of the MN site B (fec0:0:0:100::/64): a foreign site. => please add zone IDs to scoped addresses. If the MN moves from the site A to site B, the MN cannot determine the direction to which it should send a packet destinated to fec0:0:0:100:1234:5678:9abc:def0. The destination address can be both on the site A and the site B. => Jinmei, can you explain the scoping architecture to your colleague? It seems I'll be impolite if I try to answer (:-).
