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. These comments should be treated just like any other last call comments. This draft concerns dynamic LDP capability announcement and withdrawal. It's Security Considerations section simply refers to RFC 5306, the LDP Specification. While it doesn't seem to me that RFC 5306 offers much security, mostly saying only talk to people you trust, this referral from draft-ietf-mpls-ldp-capabilities-03.txt appears to correctly summarize the security considerations for this draft. nits: Section 2, fourth dash point OLD - Includes an IANA considerations section that requests IANA for assignment of code point for the optional parameter corresponding NEW - Includes an IANA considerations section that requests IANA assignment of a code point for the optional parameter corresponding Section 3: 2nd paragraph: insert "a" or "the" after "The format of".
