Hi,   I have reviewed draft-ietf-6man-ipv6-mibs- obsolete-01 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 document contains versions of several obsoleted MIB modules (IPV6-MIB, IPV6-TC, IPV6-ICMP-MIB, IPV6-TCP-MIB and IPV6-UDP-MIB) for the purpose of updating the MIB module repositories.   An RFC 5706 review does not apply, as this is not a new protocol or extension of an existing protocol.   There is no operational or manageability issue with this document. At best it can clarify the status of MIB modules in the repositories which is a good thing.   I have however the feeling that it’s kind of an overkill to republish MIB modules just to change their status clause. Do we really need to copy all the original MIB modules? Will we do this in the future with all MIB modules that have been and will be obsolete? Same about the YANG modules?   Also the statement in the motivation section that ‘the original RFCs (as is normal IETF policy) never changed from being Proposed Standard’ is not true for RFC 2454 which is marked in the RFC Editor pages as ‘ Historic (changed from Proposed Standard   June 2005 )’   I suggest to consider simplifying the document by dropping the current sections 2-6.If this issue was already debated and there was a strong demand from operators to republish the full MIB modules texts in a new RFC, I would be glad to look at some references.   Regards, Dan
