Dear APOPS,

RFC 8195 "Use of BGP Large Communities" was just now published:

https://tools.ietf.org/html/rfc8195

RFC 8195 presents examples and inspiration for the operational application of Large Communities. The document suggests logical categories of Large Communities and demonstrates an orderly manner of organizing community values within those categories to achieve typical goals in routing policy. Any network or route server operator can consider using the concepts presented as the basis for their own 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 RFC1997 BGP Communities. The RFC draws on the experience of operator communities such as NANOG and NLNOG.

A ton of open source implementations [1] with Large support are already available. And with more traditional vendors like IOS XR, Junos, Arista & Nokia having releases around the corner, I hope this will be useful when planning your Large Communities deployment later this year.

Kind regards,

Job
