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.





        Please note that due to the fact that this is an update to 4996,
        this review covers only the diffs to RFC4996 and not the whole
        overall standard. 





        As far as I could see the accumulated verified errata have been
        included successfully. 


        Furthermore, to my understanding the proposed updates/changes do
        not require any new security considerations. 





        Best regards, Tobias
