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
        with the intent of improving security requirements and
        considerations in IETF
        drafts.

  

Comments not
        addressed in last
        call may be included in AD reviews during the IESG review.

  

Document editors and WG
        chairs should treat
        these comments just like any other last call comments.




 




This
        document is intended to clarify RFC 5584, which describes BFD
        for MPLS LSPs
        (try saying that quickly 5 times!).




 




I
        didn’t find any security problems with this very brief document.
        




The
        Security Considerations section refers to the RFC being
        “clarified” and
        additionally cites RFC 4379. RFC 4379 contains a reasonable
        Security
        Considerations section. RFC 5584 contains a 1-paragraph Security
        Considerations
        section that cites 4 RFCs: 5880, 5883, 4379, and 5290. RFC 5880
        is the base
        document for BFD, and it contains a 2-page Security
        Considerations section,
        although several portions of the text are out of date. RFC 5883
        contains a
        trivial, 1 paragraph Security Considerations section. RFC 4379
        contains a
        decent 1-page Security Considerations section. RFC 5290 is the
        MPLS/GMPLS
        Security Framework, a substantial document discussing security
        for MPLS. 




 




Considering
the
        focus of this document and its 6-page length, its references to
        the
        Security Considerations sections of the other RFCs suffice.
