Document: draft-ietf-teas-yang-te-topo-20 Reviewer: Russ Housley Review Date: 2019-05-02 IETF LC End Date: 2019-05-15 IESG Telechat date: Unknown 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, and the guidelines require normative references to [RFC5246] and [RFC6536], among others. These two RFCs do not appear in the references. Minor Concerns: None Nits: The TOC contains several lines where the heading goes past the column of page numbers. Reformatting would make this much easier to read.
