Reviewer: Roni Even Review Date: 2017-10-15 IETF LC End Date: 2017-10-13 IESG Telechat date: 2017-10-26 Summary: The document is almost ready to be published as a standard track RFC Major issues: Minor issues: 1. In the document I noticed that key words like recommended are sometime written in upper case letters and sometime in lower case. is there a reason?. I suggest that in section 2 reference RFC 8174 and verify that normative text is in upper case letters. 2. In section 3.3 I think the text suggests transition period of couple of years. I think that it would be better to just say that both mechanisms SHOULD be supported and delete the sentence about transition period. I also wonder why is it a SHOULD and not a MUST, in which case both mechanisms will not be supported. Nits/editorial comments: 1. In section 3.4 what is "gracefully close" is there a reference? 2. In section 4 fourth bullet what is near term? I assume that as long as there is no other document that says otherwise MSPs SHOULD also provide it. 3. In section 4.1 " password sent as cleartext SHOULD be required to change" I think it means "MUST change"
