Actually it doesn't suffer from this problem. You just wind up getting a prefix delegation per edge router, and when you get a delegation, you add that edge router to the list of routers to which you will relay downstream prefix delegation requests. You do not need spanning tree because if you reach the same router through two different paths, you will just get the same delegation twice per DUID/IAID. The reason homenet didn't go with this solution is essentially that HNCP has a better feature set and is easier to make work in a homenet environment. (To be clear, I am just explaining the prefix delegation model. If Anima doesn't want to do it that way, that's fine with me, just as it's fine with me that homenet went with HNCP.) _______________________________________________ homenet mailing list [email protected] https://www.ietf.org/mailman/listinfo/homenet
