Barry Leiba has entered the following ballot position for draft-ietf-babel-source-specific-07: No Objection When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-babel-source-specific/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Thanks for an easy read. I have only some minor comments: — Section 5.2 — Please expand “AE” on first use. You should also do the same in Section 4.1.4 of draft-ietf-babel-rfc6126bis. A node MUST NOT send a wildcard retraction with an attached source prefix, and a node that receives a wildcard retraction with a source prefix MUST ignore it. The “it” here is ambiguous: please specify “MUST ignore the source prefix” or “MUST ignore the retraction”. The same comment applies also to the subsequent paragraph. — Section 6.1 — For what it’s worth, I don’t find the diagram to add anything to the text, and I wouldn’t have a clue what the diagram was trying to say without the text. Packets destined to D but not sourced in S will be forwarded by A to B, and by B to A, causing a persistent routing loop That text is describing not what will happen with this standard, but what *would* happen if this standard didn’t correct for it. So please change “will be forwarded” to”would be forwarded”, or perhaps “would then be forwarded”. And in the previous sentence, change “merely ignores” to “merely ignored”. These make it clearer that they’re talking about a hypothetical situation that’s counter to what’s specified herein.
