In either case, it's important to make the distinction between prefix assignment and prefix delegation. In an autonomous network, I don't think it's practical to do hierarchical prefix delegation. That has the unfortunate consequence that there can't be any routing aggregation. The delegating router can of course _try_ to keep the topology clean, but routing has to work even if it fails. That being the case, every delegation _request_ should be for a /64, because every delegation request should be a request for a /64 to configure on an interface of a router. Whether or not aggregation occurs is up to whichever device is the delegating router. Having a distributed delegation framework is probably a good idea, but a hierarchical distribution won't work, so the idea that a router could request prefixes to be delegated and then re-delegate some of those prefixes is, IMHO, not going to work. _______________________________________________ homenet mailing list [email protected] https://www.ietf.org/mailman/listinfo/homenet
