For example, an anchor might aggregate a prefix like 2001:db8::/32 and give out ::/64 prefixes to mobile nodes. This preserves the notion of a home network that is identified by an aggregated prefix - so the global routing system can identify the home network by the short prefix. On the other hand, 'draft-ietf-rtgwg-atn-bgp' assumes that there is no such aggregation, and that the anchor has no short prefix associated with it. Then, when a mobile associates with an anchor the anchor injects the mobile's ::/64 prefix into the global routing system. If the mobile moves to a new anchor, the old anchor withdraws the /64 and the new anchor injects it instead. In other words, the system is based on complete de-aggregation and there is no notion of a "home" network - the mobile is always "away from home". This is a very different model, and naturally supports continuity of the mobile's mobile network prefix at all times due to the nature of the routing system. It provides "scalable de-aggregation", which is something that the routing research group (RRG) investigated but has not been accomplished until now. I think it would be worth considering this model both on its own merits and/or in conjunction with the dmm document. The notion of a "home network" need not be preserved, and instead we have scalable de-aggregation. Please have a look (as I did for the dmm doc) and post comments or questions.

The document went through several revisions and there were good amount of reviews on this document. The authors have addressed all the comments and there are no open issues that we are tracking at this time. We believe the document is ready for IESG reviews and like to confirm the same from the working group. The following message commences a two week WGLC for all feedback. Document Link: https://www.ietf.org/id/draft-ietf-dmm-distributed-mobility-anchoring-11.txt The target status for this document is "Informational". Please post any comments/concerns on the draft. Thanks! Dapeng & Sri
