Hello, I have been selected as the Routing Directorate reviewer for this draft. The Routing Directorate seeks to review all routing or routing-related drafts as they pass through IETF last call and IESG review, and sometimes on special request. The purpose of the review is to provide assistance to the Routing ADs. For more information about the Routing Directorate, please see ​ http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir Although these comments are primarily for the use of the Routing ADs, it would be helpful if you could consider them along with any other IETF Last Call comments that you receive, and strive to resolve them through discussion or by updating the draft. Document: draft-ietf-lisp-type-iana-03.txt Reviewer: Geoff Huston Review Date: 28 November 2016 IETF LC End Date: not called Intended Status: Standards Track Summary: I have significant concerns about this document and recommend that the Routing ADs discuss these issues further with the authors and the IANA. Comments: Draft quality and readability. The third paragraph of the Introduction is unclear. Given that LISP itself is an experimental specification it is hard to understand the distinction being made between the "experimentation purposes" and some other undescribed purpose which this reviewer can only conclude is also an experimentation purpose. I suggest re-thinking the intent of this paragraph and expressing it in simpler terms. In section 2, the use of the normative "MUST" seems to be inappropriate, particularly when a non-normative "must" ius used in section 4 in an identical context. Major Issues: It seems anomalous to me that a request to set up an IANA Registry for an Experimental Protocol (RFC6830 is Experimental) is itself proposed to be a Standards Track document. Furthermore, the document states that additional values be assigned via a Standards Action. Again, it appears anomalous to me that a specification of a parameter value of an experimental protocol be described by a Standards Track action. If RFC6830 is revised and is re-published as a Standards Track specification then these points are of course not relevant, but until such a publication takes place, specifying an IANA parameter registry as a Standards Track action for an experimental protocol seems to me to be anomalous and should not proceed unless the IESG specifically agrees with this approach. Alternatively RFC5226 could be further revised to explicitly describe the guidelines as they relate to Experimental Specifications (as distinct from experimental allocations within Standards Track specifications), as this area appears to be unclear from my reading of RFC5226. However it is not for me to resolve this issue, nor is it up to the draft authors, or the LISP working group, as far as I can tell. It is up to the IESG and IANA to clarify this situation and allow IANA to be given clear directions as to how to maintain parameter registries for experimental specifications while they remain experiments.
