review-ietf-idr-cpr-06-tsvart-lc-black-2025-01-31-00

This document has been reviewed as part of the transport area review team's
ongoing effort to review key IETF documents. These comments were written
primarily for the transport area directors, but are copied to the document's
authors and WG to allow them to address any issues raised and also to the IETF
discussion list for information.

When done at the time of IETF Last Call, the authors should consider this
review as part of the last-call comments they receive. Please always CC
tsv-art@ietf.org if you reply to or forward this review.

This document describes how to advertise colored IPv6 prefixes for SRv6
via BGP. As a routing protocol document that extends BGP, this document
does not raise any transport-specific concerns.

I noticed one nit - this draft has a strong dependence on
draft-hr-spring-intentaware-routing-using-color, which is an Expired
Internet-Draft.  That draft is cited as the source of requirements
and problem statement for this draft, and that draft is cited twice in
the Operational Considerations section as a foundation for guidance to
operators.  I strongly encourage the authors to find a better reference
for these purposes than an expired Internet-Draft and/or include more
material on these topics in the absence of an equally useful reference.
