Hi, OPS-DIR, Authors, I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last call comments. This Standards Track document defines a YANG data model for management of IP implementations. It includes configuration and system state. This document obsoletes RFC 7277. As a Bis document, this document is well written. It is ready with minor issues. Major issue: no. Minor issue: no. Regards, Sheng
