 “I think that the IETF *functional requirements* question is really:
   Can an implementer make it per-interface without having an impact on
   the implementation in other nodes?

 If the answer is, there is no impact, then it really doesn't matter.
 Other "ip-forwarding" settings have been described as per-router and
 generalized into per-interface many times before.

 I have added your comments to ticket #103, which I re-opened.
 I will close it again today --- I would appreciate comments in the mailing
 list as to whether there is anything to fix here.”

 “Experience shows that tuning parameters are not always exposed by a
 given implementation and even when they are, they are most likely left
 at their default value.

 My concern is that the suggested default for this parameter may lead to
 suboptimal behavior on non-LLN links (by ensuring straight flooding for
 some number of intervals).

 Even if there is "room for interpretation" on considering this a per-
 interface
 parameter, the correct default needs to be specified in this draft or else
 a
 BCP or something will be necessary.

 It would be good to hear Jonathan's opinion…”
