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 Early Review/Last Call comments that you receive, and strive to resolve them through discussion or by updating the draft. Document: draft-ietf-pce-pcep-flowspec-05.txt Reviewer: Acee Lindem Review Date: 10/22/2019 IETF LC End Date: N/A Intended Status: Standards Track Summary: This document is basically ready for further discussion and WG Last Call, but has nits that should be considered prior to publication. Comments: The draft is extremely easy to read and understand. This is an early review yet the document is in better shape than most documents I review during Working Group Last Call. I don't even follow the PCE Working Group but believe I could consume the entire draft with only a rudimentary understanding of the PCE protocol and having read and followed RFC 5575. Major Issues: None Minor Issues: None Nits: I have a question and a few suggestions: 1. For the multicast flow filter TLVs, is there some reason why the S-bit and G-bit respectively indicate that the fields are NOT used? In most protocol encodings, a Set bit indicates that a field is used and a Clear bit indicates that it is not used. Also, all zeros has also been used a wildcard specification but I guess you preferred something explicit. 2. For IGPs, we always hyphenate Bit definitions. However, in this specification, the Bit definitions are not hyphenated other than in the IANA section. Being the LSR chair, I'd prefer consistency with the IGP specifications. 3. In most IETF specifications, "headend" is a single compound word. 4. In section 9, could you indicate that the only change is adding the <flowspec-list>? This seems to be the case but it would be good to state it explicitly. 5. I have attached an RFCDIFF of suggested editorial changes. Thanks, Acee
