Re: [Bier] WGLC for https://datatracker.ietf.org/doc/draft-ietf-bier-frr/

ETOOLATE (past 2 weeks i guess), but still:

I have read the draft and support its publication.

Wrt. to the necessity: This document is well written and describes the different
options IMHO thoroughly.

I have not followed the prior discussion, but to answer the points Tony raised below:

Is it necessary ? I think yes. I consider its really nice dual purpose document for and against BIER FRR:

If somebody is asked to implement FRR for BIER, i think the document supports the right 
level of detail we can give without assuming specific forwarding plane implementation/optimization
options. If someone instead wants to avoid having to implement BIER FRR, then the document
also support that goal by elaborating on all the complexities, analysis and limitations
the FRR solution would have.

Does it need to be standardized/published ? Well, it only targets informational, because i think we can
make the argument that it does not introduce new on-the-wire interoperability requirements
(arguably for tunnels, but that's fine).  And if i was a customer told by a vendor that they had
perfect working BIER-FRR, then i would know a lot more questions that i would need to ask how it
was implemented/how it works so i can troubleshoot it, after reading this draft.

So, thanks a lot to the co-authors and contributors for this work. I think its a good
thing for BIER overall if we have this out as an RFC.

Cheers
