Reviewer: Shawn M. Emery
Review result: Ready with numerous nits

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.

This draft specifies new Information Elements (IEs) in order to support BGP
community
information for the IP Flow Information eXport (IPFIX) protocol.

The security considerations section does exist and states that the draft
just defines
new IEs and does not introduce any new security considerations.  The
section then
goes on to state that the same security issues that apply to the IPFIX
protocol and
the corresponding Information Model applies to this specification.  I agree
with these
assertions.

None.
