SECDIR review of draft-ietf-ospf-manet-single-hop-or-03   I 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, WG chairs and ADs should treat these comments just like any other last call comments.   As per the Abstract, this document describes use of the OSPF-MANET interface in single-hop broadcast networks. It is targeted as an Experimental RFC. It is a very brief I-D, only 8 pages. It updates RFC 5820 ( Extensions to OSPF to Support MANETs) to describe use of the MANET interface in single-hop broadcast networks, consistent with the abstract.   The Security Considerations section contains only one sentence, stating that there are no new security considerations beyond those expressed in RFC 5820. Since this is an update to that RFC, this text makes sense. RFC   5820 contains a two-page Security Considerations section. Much of the text from that section is taken from RFC 5614 ( MANET Extension of OSPF). The Security Considerations text in 5820 is well written and is intended to address a broader range of MANET contexts that the single-hop broadcast networks address here. Thus citing that text in this document seems adequate.
