Hi Acee,
we require strict ordering - it may not be necessary now, but in the
future we may introduce something that will need it, so we started to
enforce it from day 1.
thanks,
Peter

I have reviewed the draft and support moving ahead with publishing this as an
RFC.
The primary use case is well described in Section 3 of the draft. Note this is
NOT, as some folks have mistakenly inferred from the draft title, aimed at
multicast RPF use cases.
As regards the evolving set of rules for flex-algo calculations, I think the
current model of adding an appendix with the full list of updated rules is
problematic.
We now have three documents which define rules:
RFC 9350
draft-ietf-lsr-flex-algo-bw-con
draft-ietf-lsr-igp-flex-algo-reverse-affinity
Each document is accurate based on the rules defined at the time of publication.
But as each document is published - with potentially more on the way - it becomes
difficult to know which is the "latest".
Readers of one document might not be aware of the other documents.
Perhaps the authors of the two drafts above could consider introducing an IANA
Registry which has the ordered list of rules (and appropriate references for
each) so that there is one source of truth.
Each document would then simply specify the updates to the IANA registry.
I don't think we need this, since all the interface constraints need to be
satisfied for an interface to used in a given flex algorithm, I don't see that
the ordering of the rules is important.
Maybe the text in the two flex-algo drafts which are going to progress and be
published shouldn't imply strict ordering.
Thanks,
Acee
