Hi Hao, Thanks for your review. Please see inline.

[Wei] In the draft, I mean the AAA server compares the recieved message with the database to verify the legitimate user. Modifying this to "it validates the sending client" should be better. > * If mB4 using DHCPv6 Solicit just for lease query, instead of IP > address, the access request will always be send to AAA-server?

[Wei]: IMO, in NAS, the recieved DHCPv6 solicit message will trigger the RADIUS request and then get all attributes including Multicast-Prefixes-64 from AAA server. NAS will save them locally. If mB4 using DHCPv6 Solicit just for lease query(I'm not sure DHCPv6 Solicit can be used for lease query according to rfc5007), NAS will not send RADIUS request because it had saved these attributes before. > * In Lightweight 4over6 scenario, lwB4 ([I-D.ietf-softwire- > lw4over6]) as the client of DHCPv6 and DCHPv4o6 to request it's IPv6 > & IPv4 address respectively.

[Wei]: So far, this does not take into consideration about what will occur between NAS & AAA server under the scenario of two different DHCP-servers co-exist at the same time. I'm glad to take further consideration and solicit your proposal. > > Section 4.1: > * The priority of Multicast-Prefixes-64 in Access-Accept message > is higher than pre-provisioned?
