Hello

Here is one comment about using MR-HA tunnel for DHCP-PD.

In this draft, the MR registration processing needs 3 round trip between MR and HA.
i. BU to HA; (getting and binding MR_HoA)
ii. DHCPv6 message over MR-HA tunnel. (getting MNP)
iii. BU to HA; (binding MNP)
While, if PD is combined within BU, it is only 1 round trip.

>From implementation of viewpoint, the later seems well done prior of the former. Maybe I have lost something, can anyone tell me the story why we gave up the latter in the new version? Thanks.

B.R.
Yungui
