OK, but I don't think there is a good way to associate a specific MPL datagram with a DODAG ID, so a node can determine which scope 3 that MPL datagram is associated with. And, using DODAG ID tightly couples MPL with RPL, when MPL as currently defined can be used without RPL. I think scope 4 is a much better candidate for the "composite" subnet use case, while scope 3 is good for a single physical mesh. - Ralph > On the other hand, > the routing layer could take the same physical setup and treat it > as distinct 802.15.4 meshes with PLC interconnects, in which case > you would get multiple 0x03 scopes. > > I shall not today attempt further to define 0x03 scope; and > perhaps I could never succeed in intelligibly doing so.
