Document: draft-ietf-teas-yang-te-topo-15 Reviewer: Russ Housley Review Date: 2018-05-17 IETF LC End Date: 2018-05-30 IESG Telechat date: 2018-06-07 Summary: Not Ready Major Concerns: See https://trac.ietf.org/trac/ops/wiki/yang-security-guidelines. The Security Considerations section MUST follow the template provided on that web page, but it is not followed by this document. Note that [RFC5246], [RFC6241], [RFC6242], [RFC6536], and [RFC8040] are required to be normative references by those guidelines. None of these appear in the references. Minor Concerns: Section 1.1: Please update the first paragraph to reference RFC 8174 in addition to RFC 2119, as follows: The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here. Section 1.1: Please add a reference to RFC 7926. Nits: Please pick one spelling (YANG vs. Yang) and use it throughout the document. The TOC contains several lines where the heading goes past the column of page numbers. Reformatting would make this much easier to read.
