+1 basically 1st, it is advised for the draft to validate that their assumptions as to packet processing and IPv6 conformance hold, refer to questions raised among others in IETF 105 meeting minutes (if I record correctly). 2nd,yes, we should focus on the requirements document at this point in time state of which leaves a lot to be desired IMO. I will dig out my old comments in next days and let's work on this. --- tony On Tue, Mar 17, 2020 at 10:38 AM Greg Shepherd <gjshep@gmail.com> wrote: > Mike, > > On Tue, Mar 17, 2020 at 9:27 AM Michael McBride < > michael.mcbride@futurewei.com> wrote: > >> Hi Greg, >> >> >> >> *>*To date, there has been insufficient support on the list to adopt the >> draft. >> >> >> >> We won’t know unless we ask the WG. >> >> >> >> >It is the BIER WG position at this time that a review by the 6man WG >> should take place before any further discussion in the BIER WG. >> >> >> >> You mean the bier chairs position.
