I have reviewed this document as part of the INT area directorate's ongoing effort to review all IETF documents being processed by the IESG.

The document, in version 12, is well written. The objectives of the draft are clearly stated, and relate to the requirement stated in RFC 9350 to describe in specific document each extension of Flex-Algorithm beyond SR-MPLS and SRv6 data-planes. The draft's structure is borrowed from RFC 9350 and describes forwarding or operational considerations. 

In my view, the document is ready to be published. I only have one minor comment that the author might ignore as it may stem from my inexperience with IGP Flex Algorithms. As far as I can tell, the metrics that can be used in flexalgo can be rather dynamic. Given this dynamicity, what is the policy that should be adopted in case the metric for a given prefix is updated very frequently? IGP convergence can take time, and consumes resources on the routers, and I was wondering if there would be some sort of threshold or minimum time before an update is considered.  

Nits from the Gen-ART review have been addressed in version 12.
