Reviewer: Watson Ladd Review result: Ready 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. This document describes a small extension to OSPF to include information of the originating router for a prefix, which otherwise would be lost as the prefix proceeds to be readvertised. This information is quite useful when determining what is going on under trying circumstances. Sincerely, Watson Ladd -- last-call mailing list last-call@xxxxxxxx https://www.ietf.org/mailman/listinfo/last-call
