Please see measurements below on Regular, Extended (EC), and Large Communities (LC). Analysis is based on data from many newer Routeviews collectors. ** Question: Any insights why we don't see any ECs at all? ** OTOH, we do see good numbers of LCs even though there is no IANA registry for them yet. Distribution of path lengths in updates with Communities/LCs is also shown below.
Sriram P.S.
