it would seem that we only have 3 choices once we run out of /64s to give out on links that for whatever reason we cannot bridge on.
1. No IPv6 2. NAT IPv6 3. MLSRv2 (if what you propose works, I don't yet see why it wouldn't) I think this is a case of what is the least bad option. We shouldn't ignore the problem though. - Mark On Oct 9, 2011, at 6:38 PM, Ole Troan wrote: > Erik, et al, > > to expand on the ideas I presented on MLSR (or rather MLSRv2 as it hasn't > really been described anywhere) as a method for numbering a routed home. > please let me be clear that I'm not convinced this is a good idea. i.e. why > not just get < /64? > I do think we could get something working though. > > routers can be in an arbitrary topology. all routers running a routing > protocol. > the site prefix (/64) is either advertised in the IGP with a new LSA or > proxying of RA messages is done (split horizon). > a router advertises the same /64 prefix (in a PIO) on all of its interfaces. > L bit is 0. > > the link model here is that all hosts are off link from each other. > link-local scope is restricted to only the physical link. multicast > link-local scope as well. > > a host uses SLAAC (or DHCP) to create an address, then does DAD as normal. > the first hop router uses it's routing topology database > to check for conflicts. similar mechanisms described in SAVI are used to > glean address information from the host. the SAVI binding > database is then used to inject host routes into the IGP. > > this requires no flooding of ND, or any other changes to on-link protocols > for loop detection. no changes in hosts either. > only downside is that it requires a host to have sent a packet of some form > for the SAVI binding to be initiated. > it might also be possible to support host mobility with the home with this > mechanism. > > cheers, > Ole > > _______________________________________________ > homenet mailing list > homenet@ietf.org > https://www.ietf.org/mailman/listinfo/homenet _______________________________________________ homenet mailing list homenet@ietf.org https://www.ietf.org/mailman/listinfo/homenet
