I am an assigned INT directorate reviewer for https://datatracker.ietf.org/doc/html/draft-ietf-6man-snac-router-ra-flag-02 These comments were written primarily for the benefit of the Internet Area Directors. Document editors and shepherd(s) should treat these comments just like they would treat comments from any other IETF contributors and resolve them along with any other Last Call comments that have been received. For more details on the INT Directorate, see https://datatracker.ietf.org/group/intdir/about/ The document defines a new IPv6 ND Router Advertisement (RA) flag, the "SNAC router" flag, which SNAC routers use to identify RAs sent by other SNAC routers. This is a rather simple (although incomplete at the moment, potentially waiting for IANA assignment) definition of a flag. According to reference [draft-ietf-snac-simple-05], the flag is a bit inside the RA flags field. For completeness, I think the full definition should be included in a single document (e.g., in this document draft-ietf-6man-snac-router-ra-flag), and not duplicated. The behaviour of the SNAC router to use this flag is defined in reference [draft-ietf-snac-simple-05]. On the other hand, some behaviour of non-SNAC routers is described in this document draft-ietf-6man-snac-router-ra-flag. I’m not sure if this behaviour modifies/updates RFC 4681 and 5175? If so, more information is needed. If not, a reference would be more appropriate.
