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.

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.

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).
