Last Call Review of draft-ietf-sidr-origin-ops-21
review-ietf-sidr-origin-ops-21-secdir-lc-yu-2013-11-21-00

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.

Summary: Ready with nits.

The Security Considerations section appears to accurately document the
significant limitations of Route Origin Authorizations.

There should probably be an example of the sort of privilege
escalation attacks that can result from incautious Local-Preference
attributes.

Editorial:

In Section 4, "along with it's traffic engineering characteristic(s)",
change "it's" to "its".

Section 5 mentions a block 10.0.666.0/24, which is somewhat
distracting because that is not a valid IPv4 address block.
