In my opinion it's a very good draft and I agree it would be a good idea to try to reduce broadcast traffic for ND.For this reason, the "white board" approach is very appealing, but I have some questions about it... Tell me if I'm wrong: the main idea is that there is a logical centralized "white board" that includes all the IP addresses from multiple PANs. But what happens within a PAN when a backbone router crashes? How can a node get routing info about other nodes belonging to its same PAN if it can't access the white board residing on the crashed backbone router? The nodes may keep their own routing cache, but this is not a completely reliable approach. Is that point interesting for the WG? (maybe is out of scope of this specific draft) Let me know if you have any thoughts about this (or if this problem it's been yet analized by the WG :p) Regards Giorgio<<winmail.dat>>
