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 have one technical issue with the document. In my opinion, the document would benefit from a little more detail regarding how the binding table is used for filtering. Even a sentence to the effect of “It is beyond the scope of this document to describe the details of the filtering mechanism and its use of the combined SAVI binding table.” would be helpful. In section 7, I don’t understand “the principle of decision is reasonable” Can this phrase be reworded for clarity? The document needs a review for consistency, english language usage and spelling. For example, this sentence appears in section3: If more than one SAVI method is enabled on a SAVI device, the method is referred to as "mix address assignment method" in this document. but the phrase "mix address assignment method" appears nowhere else in the document. - Ralph
