I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. Document editors and WG chairs should treat these comments just like any other last call comments. This document aims to be an Informational RFC describing security problems with various routing protocols. Aside from various spelling and other nits that the RFC-Editor can easily handle, I have no issues with this document and it is ready for publication. Nico --
