Moin! I am an assigned INT directorate reviewer for . These comments were written primarily for the benefit of the Internet Area Directors. Document editors and shepherd(s) should treat these comments just like they would treat comments from any other IETF contributors and resolve them along with any other Last Call comments that have been received. For more details on the INT Directorate, see http://www.ietf.org/iesg/directorate.html. I've read the document and see no issues with it. One minor nit that might clarify things is in section 3 when explaining option length. This is in octets while the other lengths in the option are bit mask. Might be worth spelling out. So long -Ralf
