Export of BGP Community Information in IP Flow Information Export
RFC 8549, “Export of BGP Community Information in IP Flow Information Export”, is a Proposed Standard document published in April 2019 by Z. Li, R. Gu, J. Dong. The canonical text is published by the RFC Editor.
Abstract
By introducing new Information Elements (IEs), this document extends the existing BGP-related IEs to enable IP Flow Information Export (IPFIX) to export BGP community information, including the BGP Standard Communities defined in RFC 1997, BGP Extended Communities defined in RFC 4360, and BGP Large Communities defined in RFC 8092. According to the network operator's BGP community planning, network traffic information can then be accumulated and analyzed at the BGP community granularity, which represents the traffic of different kinds of customers, services, or geographical regions. Network traffic information at the BGP community granularity is useful for network traffic analysis and engineering.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
