Reviewer: Sheng Jiang Review result: Has Nits 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 standard track document defines a new option Local Interface Identifier in OSPF Hello and Database Description (DD) packets as an extensions to OSPF link-local signalling. This document is short and well written. It is READY with a couple of Nits, which should be easily fixed. Major issue: no. Minor issue: no. Nits: Unused Reference: 'RFC8379'. There is no relevant text. Either some text should be added or this reference should be deleted. In the IANA section, "18 - Local Interface Identifier TLV". Normally the value that is actually assigned should be left to IANA. Here, it should be TBD as a draft. Regards, Sheng
