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 informational document is as straightforward as we are ever likely to see. It is three pages long (almost squeezed into two, which I would not have thought possible). It instructs IANA to mark two BGP path attributes as deprecated where the corresponding documents are an RFC already reclassified as Historic and and abandoned I-D. It's a database clean-up with no security implications. Radia
