I have reviewed this document as part of the Security Directorate's ongoing effort to review all IETF documents being processed by the IESG. Document editors and WG chairs should treat these comments just like any other last call comments. The summary of the review is Almost Ready. This document specifies an extension to the stateful Path Computation Element Communication Protocol to associate two or more Label Switched Paths for the purpose of setting up path protection. This is not at all my area of expertise. The Security Considerations section primarily refers to the Security Considerations in existing RFCs and one draft, draft-ietf-pce-association-group (which is already in the RFC Editor queue). I think these references are pretty thorough and provide good security coverage and advice with one possible exception. Given that this document specifies a new facility, it seems likely that a few narrow sentences would be in order about the damage an adversary could cause by specifically monkeying with that new facility. Tiny nits: In abstract and other places when referring to what this standards track draft does: "describes" -> "specifies" or "defines" Draft references draft-ietf-pce-association-diversity-08 when latest version is -09 Thanks, Donald =============================== Donald E.
