Hi Anders and Mukul:
For RPL, we probably need more than one bit. RPL needs a TID, and an instance ID will help quite a bit in some cases if the app is aware of it. Other routing protocols might benefit from other information to improve their operation. Once we figure what the abstract information is, then we'll probably have to define a way to carry that information from the host to the router. Might be ND, but other people have already started a packetBB / RPL interwork, so at this point I do not know.

RPL is one routing protocol, but 6LoWPAN may run under any routing protocol - or none at all. In all cases, a sleeping node can benefit from asking a neighbor router to provide connectivity to that node. To me this definitely sounds like a feature that belongs to the 6LoWPAN ND toolbox.

I agree. That's why I think 6lowpan ND should provide a mechanism to clearly identify a registered neighbor as a 6lowpan host or a 6lowpan router.
