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. The Security Considerations section is a bit light, but addresses the matter. The only nit I found was that in the Security Considerations section, the use of TLS for securing the PCEP session is "recommended". I think that's a BCP 14 keyword so should be "RECOMMENDED". (I don't think that's significant enough to change the summary to Has Nits.) Best regards, Chris
