The name of the new draft isn't all that important, other than it should accurately reflect the content of the draft. The author's name gets dropped once adopted anyway, so I'm not certain why there would be concern for who's 'taking' who's work. Especially since the discussion and documentation of the described mechanisms have a history in the WG: 1. When draft-chen was first presented, it was pointed out that draft-merling was already there: http://www.youtube.com/watch?v=3DAuzdpgePomA&t=3D33m51s and it was sugge= sted to have a combined draft. 2. While draft-merling does not talk about LFA based, the authors and some vendors/operators discussed LFA based FRR back in 2019. Michael mentioned it in this email https://mailarchive.ietf.org/arch/msg/bier/VRYfB7S7g7xuooIwV9XQDAW56hU/, and it was already covered in their paper https://atlas.informatik.uni-tuebingen.de/~menth/papers/Menth20c.pdf (the link was in that email as well). Considering this history, the honest approach would be to submit the combined draft as a new submission. This new draft should be as all inclusive as possible of the FRR mechanisms for BIER. If there is nothing documented on the wire then the draft should be Informational. And as an Informational draft on FRR for BIER, there needs to be a section on how the BIER architecture relies on unicast reachability; ie, BFIB is built from the UFIB, and any FRR mechanism for unicast will be inherited by BIER. Then the case, and mechanisms described for non-IGP based BFIB will have context, and the draft will be a one-stop, comprehensive Informational document on BIER-FRR. The recommendation to have Jeffrey hold the pen as Editor, was rooted in this expectation of a comprehensive draft. And to date, only Jeffrey Zhang and Greg Mirsky have constantly expressed this same goal of including a section documenting current IGP-based FRR mechanisms inherited by BIER. I have not discussed this with Greg, but I'm putting his name out there as another potential Editor/Author to assist in meeting the WG goals of a comprehensive draft. Pick one or not (if they are willing to help..), the WG goals for the draft remain. Eventually the Authors' list will need to be edited, but that is not required for adoption, of course. Again, pick now, or pick later. It will be up to the list of combined Authors to decide who stays at the top. The recommendation to keep the Authors' names at the top from filling the page should be nothing new to anyone who has gone through the draft->publish process in the IETF. I hope this clarifies the recommended direction for this work and these drafts. Thank you all for staying engaged and contributing to the process.

I think it's a good addition within the architec= ture for the case IGP is not used for signalling, e.g. when controller or s= tatic programming.

=C2=A0

The draft must however explain in what scenarios it = is used and quote the according IGP drafts to guarantee loop-free behavior = (well, BIER will tie-break loops but we'll have 1x microloop & poss= ibly not deliver payload if BIER FRR is not properly computed/intsalled). With that the draft should also pay attentio= n to how the function is deployed/updated network-wide if IGP is not presen= t
