Reviewer: Tero Kivinen 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. This document specifies how to add extensions to Babel routing protocol so that it can route IPv4 packets over network core without IPv4 addresses. Its security considerations section do mention the fact that this feature might invalidate the assumptions made by the network administrators, and suggest packet filters to mitigate this issue. I think the current security considerations section covers issues caused by this extension. -- last-call mailing list last-call@xxxxxxxx https://www.ietf.org/mailman/listinfo/last-call
