Several implementations of Large BGP Communities are now available, and a playground has been created as well. The goal of the playground is to provide an easy way to get several implementations running, so that anyone can explore the feature. Docker images are available to get the implementations up and running quickly. The playground currently includes ExaBGP, GoBGP and BIRD, and the README has detailed instructions on how to configure everything.

Some initial interoperabilty and compliance test results are also available. Pierky’s preliminary testing in the playground discovered a cosmetic bug in BIRD and a missing feature in GoBGP! Awesome work.
