BGP Large Communities: RFC 8092

Well… seems I have been sleeping for a while. Draft BGP Large Communities about which I wrote a little while ago here already go to it’s final stage about a month ago. RFC 8092 was published mid February/2017.

Looking at the differences between draft 06 (published October/2016) and RFC 8092 little was changed except for small language corrections and the “Reserved Large BGP Community values” section.

Will you be able to play with Cisco routers? Not yet! The “big ones” like Cisco and Juniper have not implemented any draft or the RFC. But if you want to stay updated please keep looking at the implementations page. IXPs (Internet Exchange Point) thatfrequently use servers running opensource routing software can already upgrade their code and start testing and defining policies and community values. This Internet Draft is a good start.

To better understand what this new BGP attribute is, have a look at my post from 2016: Large BGP Communities (Internet Draft).
