But I think that some points are to be clarified in MIPv6 when the MN is multihomed. That is what we are trying to show in draft-montavont-pb-statement. And I'd like to point out another aspect of multihoming, more linked to our draft on filtering (draft-montavont-mip6-ha-filtering). Assume that you have two interfaces, a WLAN interface and a GPRS interface and you currently use the WLAN interface through a reverse tunnel with your home agent. Assume that you receive several flows on your pda. One of them is a video streaming. Then you leave the hot spot zone and want to switch your flows on GPRS interface. To do so, you send a BU to your HA. In this case, it can be very useful to add some filters on what flows you want to be redirected and what flows you don't want on your GPRS interface. It seems to me that to use the BU in that case is a good solution, because you only need to send one message. This does not forbidd the use of other mechanisms to manage multihoming in different situations. Maybe the conclusion of that can be that different problems may lead to different solutions. A clear problem statement, from each WG may definitly help to clarify the situation.
