Hi Alvaro, Thank you very much for your detailed review! And thank you for your guidance for the modification! We will have a discussion about the modification and modify the draft as soon as possible. :-) (Sorry I cut some details because the mail scale limitation.) Best regards, Sandy 原始邮件 发件人:AlvaroRetana <aretana.ietf@gmail.com> 收件人:draft-ietf-pim-dr-improvement@ietf.org <draft-ietf-pim-dr-improvement@ietf.org>; 抄送人:pim-chairs@ietf.org <pim-chairs@ietf.org>;pim@ietf.org <pim@ietf.org>; 日 期 :2020年06月16日 05:45 主 题 :[pim] AD Review of draft-ietf-pim-dr-improvement-09 Dear authors: Hi! I hope everyone is safe and healthy. I (finally!) finished my review of this document. Thank you for the effort so far. I think that this document is not ready and needs significant work to move forward. There are many parts that are repetitive and redundant. Also, there would be a lot of benefit from an English-language edit/review. I tried to cover many of the points in my comments, but probably left some out... Before getting into the details, I have a couple of points I want to highlight up here: (1) How does this document interact with rfc8775 (PIM DR Load Balancing)? Should be BDR always be a GDR? Can a BDR not be a GDR? rfc8775 is not even mentioned. (2) As far as I can see draft-mankamana-pim-bdr has not been adopted yet. Assuming that is the plan, how would the two mechanisms interact? Given that draft-mankamana-pim-bdr doesn't add options, and §5 says that if no options are received then the routers MUST use rfc7761, how does a router implementing this specification tell the difference? I realize that some of these questions may be better directed at draft-mankamana-pim-bdr, but because the WG agreed that a statement relating the two should be included in this document [1], then I'm asking now. I would really like to understand what the WG expects. (3) The Shepherd writeup [2] says that there is an implementation and deployment of this specification. *But* the IANA Considerations section lists the code points as TBD. What's the status of the implementation? Are there specific code points that should be suggested to IANA? An rfc7942-type section would be useful to justify specific code points, if needed. (4) The election algorithm (§4.2) is a word-by-word copy from rfc2328! It is good to reuse technology, but in this case (1) the description is out of context, and (2) the election function from rfc7761 would make a much better (and familiar) base for the description (and, as far as I can tell, should yield the same result). Please update the description. I expect a significant change in the structure of the document to move forward. Thanks! Alvaro.
