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?

Abstract
This document specifies the "Depth-First Forwarding" (DFF) protocol
for IPv6 networks, a data forwarding mechanism that can increase
reliability of data delivery in networks with dynamic topology and/or
lossy links. The protocol operates entirely on the forwarding plane,
but may interact with the routing plane. DFF forwards data packets
using a mechanism similar to a "depth-first search" for the
destination of a packet. The routing plane may be informed of
failures to deliver a packet or loops. This document specifies the
DFF mechanism both for IPv6 networks (as specified in RFC2460) and in
addition also for LoWPAN "mesh-under" networks (as specified in
RFC4944).
