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. This standards track draft describes identifiers used in Transport Profile of MultiProtocol Label Switching (MPLS-TP). The security considerations section does exist and states that this draft does not introduce any new security concerns, because it is just an informational model. The section continues that it is the responsibility of the protocol, that consumes the identifier set, to outline the various security issues. I agree with this assertion. General comments: None. Editorial comments: None. Shawn. --
