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. I did not see any special operational or network management related issue. This document is clear to me and is ready for publication. By the way, do you think "MRACL" in this document need a reference or expansion? Cheers, Tianran
