 Export BGP community information in IP Flow Information Export (IPFIX)
                draft-ietf-opsawg-ipfix-bgp-community-03

Abstract

   This draft updates RFC7012 IPFIX information model by introducing
   several information elements to enable IPFIX to export the BGP
   community information, including BGP standard community defined in
   RFC1997, BGP extended community defined in RFC4360, and BGP large
   community defined in RFC8092.  Network traffic flow information can
   then be accumulated and analysed at the granularity specified by the
   BGP communities, which is suitable for and needed by some traffic
   optimization applications located in IPFIX collector, SDN controller
   or PCE (Path Computation Element).
