Stephen Farrell has entered the following ballot position for draft-ietf-pim-rfc4601bis-05: Discuss 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-pim-rfc4601bis/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- 4601 used IPsec AH for it's MTI security. This removes that and points at 5796 which defines how to use ESP for link local addresses and with manual keying. That raises one technical question and two ickky process questions. The ickky process questions are probably best discussed between the IESG at least initially in case we don't need to bother the authors/wg with 'em. (1) I'd like to check that 5796 defines a way in which one can secure all PIM messages that are defined here in 4601bis (should one want to do that). If there are cases where PIM-SM can be used and where there is no well defined security then I think that would be a problem. And I think maybe there are such cases. Am I wrong? If not, then how does one secure those? (2) Is it ok for an IS to depend on a PS for it's MTI security mechanism? (I think it is, but yeah, someone else might not.) (3) Is it ok for an IS to not conform to BCP107? (I think it depends, and I'm not sure in this case.) - My review was based on the diff vs 4601 [1] and the abstract of 5796 which seems fairly clear though.
