Hello All, I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the operational area directors. Document editors and WG chairs should treat these comments just like any other last call comments. Intended status: Standards Track This document specifies extensions to the RSVP-TE to support Lock Instruct and Loopback mechanisms for Label Switched Paths.  The document is written well and I have found no issues with it. Best Regards, Menachem Dodge
