That's exactly what I expect from a decent upstream.
So far all our upstreams (Level3, Cogent, Tata), with the exception of
HE, provide this service.

I don't even care about receiving their communities which describe
where the prefix has been injected, since I can handle outbound
traffic more or less myself. It's a nice-to-have feature though.
It's the inbound that I cannot control without a little help from my
upstreams, hence our desperate need to send BGP communities.
