Hi, 

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

As with a number of ID’s, there is a significant amount of referencing of other RFCs/IDs - so much so, that it is difficult to get a clear understanding of what is being specified in the document itself (the diagrams are very useful - well done). However, since this ID has an intended status of Informational, the amount of referencing is probably acceptable but I would recommend that at least RFC4272 be included in the Informative References list.
