I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. The summary of the review is Ready. This document defines a YANG data model for the provisioning and management of Traffic Engineering (TE) tunnels, Label Switched Paths (LSPs), and interfaces. This model covers data for configuration, operational state, remote procedural calls, and event notifications. Security Considerations adequately covers different levels of access required for different type of data, as well as associated risks of incorrect lever of access.
