Should we? (Obviously, if a node really needs to know about RPL, it can always become a router.) If I understand you correctly, this is about hosts selecting a specific RPL instance-ID for outgoing traffic. Traditionally, IP has used the TOS byte (Traffic Class in IPv6) to select between different behaviors of the forwarding system. What is it that the host wants to say by selecting a specific RPL instance ID? Why can't the router make that selection, e.g. based on the Traffic Class and the destination address? (Another interesting question is, for incoming traffic, how a host selects which instances it wants to be part of. Is that even a useful thing to do? Would that selection be made by the host, by its first-hop router, or by some configuration agent?) It would be useful to get more information about how instance-IDs are intended to be used with RPL. On the protocol side: If there really is something that a host needs to know about RPL-specific information (instances or whatever), this could be delivered in an ND option that could very well be defined in an RPL-related document, no need to define it in 6LoWPAN-ND. Another way to set up this information would be to configure it during commissioning or using a host configuration protocol like DHCP.
