Are you actually seeing these communities being received on the other
side? This could be just a cosmetic display of which route is being
advertised to help you ID it in the local BGP table. I'd have to lab
it up myself, but AFAIK, unless you actually configure "neighbor
send-community", communities are not being send (barring the exception
of VPNv4/6, where extended communities are always sent)
