RFC 8195 "Use of BGP Large Communities" was Published!

Job Snijders

RFC 8195 presents examples and inspiration for the operational application of BGP Large Communities.


The document suggests logical categories of BGP Large Communities and demonstrates an orderly manner of organising community values within them to achieve typical goals in routing policy. Any operator can consider using the concepts presented as the basis for their own BGP Large Communities repertoire.

RFC 8195 is meant as a companion document in the same way that RFC 1998 provided a concrete real-world application for RFC 1997 BGP Communities. RFC 8195 draws on the experience of operator communities such as the North American Network Operators Group (NANOG) and the Netherlands Network Operator Group (NLNOG).

A ton of open source implementations with Large support are already available. And with more traditional vendors like IOS XR, Junos & Arista releases around the corner, I hope this will be useful when planning your Large Communities deployment later this year.
