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. 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-l3sm-l3vpn-service-model-17.txt Reviewer: Les Ginsberg Review Date: 12 October 2016 IETF LC End Date: 11 October 2016 Intended Status: Proposed Standard Summary: This is a well written and excellent document - impressive both for its attention to detail and its breadth. I have one significant concern. I have also identified a number of editorial issues. Comments: I have not followed the work on this document nor am I subscribed to the WG mailing list - so it is possible my comments do not account for some discussions that have occurred as this document progressed. Major Issues: The document mentions in Section 7 that the definition of the service model assumes that a number of YANG models for network elements will be provided. In the list is "QoS : classification, profiles". Looking at Section 5.12.2 of the document, it seems that the definitions could easily conflict with the definitions which we would expect in a network element QOS model (e.g., https://datatracker.ietf.org/doc/draft-asechoud-netmod-qos-model/ ) I wonder if it would be better to eliminate much of what is in this section of the draft and defer to the QOS config model? I would be interested in the authors views on this point. Minor Issues: None Nits: I have prepared a "marked up" copy of the draft with a significant number of recommended editorial changes. As the most expedient way to provide this is by sending the entire document - and as that is large - I prefer not to send it to such a wide audience. I will therefore send the marked up copy directly to the authors. Anyone else who would like a copy please unicast me and I will be happy to send it. Les
