Spencer Dawkins has entered the following ballot position for draft-ietf-mboned-mtrace-v2-22: 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-mboned-mtrace-v2/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- I support Mirja's Discuss ballot point on IANA. In addition, I have a few comments. I'm looking in the Introduction for an unambiguous statement as to whether this mechanism can be initiated by a source, and I'm not seeing one. Just based on the Introduction, I'm guessing not, but the Introduction starts by mentioning that it's difficult to trace from the source, so I'm confused. In section 3, I'm seeing If an implementation receives an unknown TLV type for the first TLV in a message (i.e., the header TLV), it SHOULD ignore and silently discard the entire packet. If an implementation receives an unknown TLV type for a subsequent TLV within a message, it SHOULD ignore and silently discard the entire packet. and trying to understand why these two cases are listed separately. I'm also trying to understand why they're SHOULDs, but please help me understand the differences you have in mind. I share the question about mixing IPv4 and IPv6. Is the last sentence in Upstream Router Address: 32 bits This field specifies the address of the upstream router from which this router expects packets from this source. This may be a multicast group (e.g., ALL-[protocol]-ROUTERS group) if the upstream router is not known because of the workings of the multicast routing protocol. However, it should be 0 if the incoming interface address is unknown or unnumbered. normative?
