One of the simpler YD reviews since this draft contains only a single module with a single r/o leaf augment to various other BFD module nodes. 1 module in this draft: - ietf-bfd-stability@2021-02-24.yang YANG compiler errors or warnings (pyang 2.4.0, yanglint 1.10.17, confdc 7.2.3.4) - warning: RFC 8407: 3.1: The IETF Trust Copyright statement seems to be missing - Minor issue just due to slight wording adjustment from copyright info normally used in the draft/RFC itself https://trustee.ietf.org/documents/trust-legal-provisions/tlp-5/ Module ietf-bfd-stability@2021-02-24.yang: - Contact information should follow formatting seen in other published modules. Just some minor cleanup/readjustments here. - Various augments will augment the respective 'session-statistics' container however for 'bfd-lag:member-links/micro-bfd-ipv4', 'bfd-lag:member-links/micro-bfd-ipv6' and 'bfd-mpls:sessions' these augments sit in parallel to that container. Is there any reason this is not consistent? General comments on the draft/modules: - Section 7.2: It is stated the document registers "2" YANG modules when it is infact only a single module Overall, just minor nits and view as ready from a YANG doctor review standpoint once the above is addressed
