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. Document : draft-ietf-grow-mrt-add-paths-03 Summary: Ready for publication as Proposed Standard This document simply carries an extension to BGP forward into this routing information export format. It notes in its security consideration section that including the information the BGP extension allows to be conveyed increases the detail of the network path information exposed to any recipient (intended or otherwise). I agree that it adds no further new security considerations.
