Reply to your request dated 07/02/2013 Draft Reviewed By: Abdussalam Baryun (AB) Dated: 24/02/2013 Reviewer Comment #AB2: Related to Applicability and Processing. ++++++++++++++++++++++++++++++++++++ The DFF mechanism specified in the document can either be used as "route-over" IPv6 forwarding mechanism (Mode of Operation: "route-over"), or as "mesh-under" LoWPAN adaptation layer (Mode of Operation: "mesh-under"). AB> the document should specify that these two modes must not occur in the same time. Section 3. Applicability AB> is general, not sure what is the use-case for the protocol, AB> does this protocol only for neighbor forwarding and exclude IP tunnling, then specify. Section 5. AB> mentioned RFC6130 this is for MANET so does this protocol apply for MANETs, not mentioned in section 3. Do you mean that LowPAN is similar to MANET, not sure how this protocol works in all environment? AB> how does this protocol forward without considering the IP forwarding? Should IP forward stop its function (not clear)? AB> DFF has access on <list of bidirectional neighbors> what kind of access you mean? Section 9.1 AB> how can DFF become a routing domain? it is not a routing protocol? Does this DFF work with ALL routing protocols in the IETF, please specify either ALL or which?
