The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-pim-igmp-mld-extension/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Thank you for the work put into this document. The mechanism is simple and powerful; the document is also easy to read. Please find below some non-blocking COMMENT points (but replies would be appreciated even if only for my own education). Please also have a look at Tommy Pauly's INT directorate review at <https://datatracker.ietf.org/doc/review-ietf-pim-igmp-mld-extension-05-intdir-telechat-pauly-2022-01-20/>. Special thanks to Mike McBride for the shepherd's write-up including the section about the WG consensus. I hope that this helps to improve the document, Regards, -éric # Section 3 It is unclear to me what to do when more TLV should be sent than allowed by the MTU. May/should/may not different subset of TLVs be sent over multiple packets (à la IPv6 Router Advertisement) ? ## Section 3.1 I was about to raise a DISCUSS on this issue. It appears that the E-bit is specified in this document while it was defined as reserved in MLDv2 RFC 3810, i.e., should this document formally update RFC 3810 (and possibly IGMPv3 as well)? I.e., in the header + abstract + introduction ? Also, does this mean that once the E-bit is set, then there cannot be any other extensions except TLVs ? This seems a limiting factor. ## Section 6 Indeed, a lot of small TLVs could increase the cost of processing, hence be an element of attack; but I would expect from an I-D to have some mitigation proposals.
