Got it. That’s more of a Ted question then.

The snac-router-ra-flag draft not rfc6724-update.

Sorry if that wasn't clear enough.

Thanks

Hi David, which draft are you suggesting this change be made? In the SNAC draft or the 6724 draft?

The problem is this addition contradicts the abstract of snac-router-ra-flag draft which says “This flag is used only by SNAC routers and is ignored by all other devices.” However, section 3 of snac-router-ra-flag only talks about how snac routers set and use the flag and that other infrastructure routers ignore the flag.

Therefore, I suggest a minor change in the abstract of snac-router-ra-flag to “other routers” instead of “other devices” leaving how hosts might use the flag silent in that draft.

Thanks

6man-

We pushed a -16 draft of the update last night. The following was updated:
1. Ted provided good updates for how a SNAC router w/ known-locals must function and provided rules in sec 5.3
2. we fixed quite a few typos

Everything else would be same as -15

6man chairs-

The authors are asking the chairs to move this forward with the shepherding document and subsequent IESG review.

Internet-Draft draft-ietf-6man-rfc6724-update-16.txt is now available. It is a work item of the IPv6 Maintenance (6MAN) WG of the IETF.

   Title:   Prioritizing known-local IPv6 ULAs through address selection policy
   Authors: Nick Buraglio
            Tim Chown
            Jeremy Duncan
   Name:    draft-ietf-6man-rfc6724-update-16.txt
   Pages:   20
   Dates:   2025-01-07

Abstract:

   This document draws on several years of operational experience to
   update RFC 6724, defining the concept of "known-local" ULA prefixes
   that enable ULA-to-ULA communications within fd00::/8 to become
   preferred over both IPv4-IPv4 and GUA-to-GUA for local use.  The
   document defines the means by which nodes can both identify and
   insert such prefixes into their address selection policy table.  It
   also clarifies the mandatory, unconditional requirement for support
   for Rule 5.5 and demotes the preference for 6to4 addresses.  These
   changes to default behavior improve supportability of common use
   cases, including automatic / unmanaged scenarios, and makes
   preference for IPv6 over IPv4 consistent in local site networks for
   both ULA and GUA prefixes.  It is recognized that some less common
   deployment scenarios may require explicit configuration or custom
   changes to achieve desired operational parameters.
