Great thank you David. I kept 7454 in the updates and made the other changes. New version now posted.
mike From: David Farmer <[email protected]> Sent: Tuesday, February 6, 2024 2:34 PM To: Michael McBride <[email protected]> Cc: Job Snijders <[email protected]>; [email protected] Subject: Re: [GROW] I-D Action: draft-ietf-grow-as-path-prepending-09.txt In looking at RFC 7454, I would argue that this document updates RFC 7454 by expanding and providing detail to the recommendation "to discourage excessive pretending in such paths" in the first bullet of Section 9, AS Path Filtering. I don't think this document updates RFC 8195, but I think the reference to RFC 8195 should remain in the introduction and be revised slightly; Old; "AS Path Prepending is discussed in Use of BGP Large Communities [RFC8195]." New; "[RFC8195] discusses using BGP Large Communities for traffic engineering through selective AS_PATH prepending." Also, by the way, I prefer David Farmer to Dave Farmer in the acknowledgment section.

Removing the updates section indeed is an option!

I don't see any reference in the draft. We probably should. Good suggestion. I was thinking updating 8195 but 7454 appears more appropriate. We will update the draft, based upon comments from last week, and add 7454 unless we hear otherwise." We didn't hear otherwise. We can remove the updates section if it doesn't make sense.

In relationship to 8195, the only sentence I see is "AS Path Prepending is discussed in Use of BGP Large Communities [RFC8195]." - which is true (8915 contains an example about prepending once), however the rest of the text in draft-ietf-grow-as-path-prepending-10 doesn't seem an 'update' in IETF document logistics parlance?
