Hello, I continue my investigations the neighbor discovery protocol for 6LoWPAN (draft-ietf-6lowpan-nd-18), and there is one point that remains unclear to me.
With 6LoWPAN, two routing mechanisms can be used : route over and mesh under. Everything is OK with the route over mechanism but I'm locked with mesh-under. In mesh-under routing, there is only two entities, the 6LBR (border router) and the hosts. Multiple hops may be needed to for hosts to reach the 6LBR. My problem is in multihop configuration : how the multicast Router Solicitation messages, used by the neighbor discovery protocol, can reach the 6LBR ? Does it depends on the routing protocol used ?
