John Scudder has entered the following ballot position for draft-ietf-6man-grand-05: 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 DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-6man-grand/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Thanks for a clear, readable, well-organized, and well-motivated document. I have just a few questions and comments below. 1. Section 5.2 The only potential impact would be for packets arriving to the router after the unsolicited NA from the host but before the rightful owner responded with the solicited NA. Those packets would be sent to the host with the optimistic address instead of its rightful owner. However most likely those packets would have been dropped anyway: creating the INCOMPLETE entry is usually triggered by traffic, so the router probably has some packets in the buffer already, dropping subsequent packets received before the address resolution is completed. Wouldn’t the buffered packets (received before the unsolicited NA) be misdelivered to the optimistic host? The quoted paragraph restricts itself to packets arriving after the unsolicited NA. 2. Section 5.3.1 Couldn’t step 4 (host detects duplication) complete sometime after step 7 (router sends NS to host)? (This might also apply to 5.3.2.) If that's possible the analysis would be a little less rosy, right? 3. Section 5.3.1 However the same behaviour would be observed if changes proposed in this document are implemented Do you mean “are *not* implemented”? 4. Section 8.4 Please add SLLAO to terminology section or expand on first use.
