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 is the rereview of the document, and the:

  Privacy considerations described in Section 11.8 of [RFC7012] SHOULD	
  be considered for all described IEs.  They export provider data plane	
  metrics which describe how packets are being forwarded within the	
  SRv6 network.

addition to the security consideration section solves my issue 
about the privacy considerations.
