Their supported communities are available from their whois; I don't think blackhole is one of them but they do have one that will allow you to suppress your announcements to remote peers of your choice if that would help. David

Does anyone know if Level3 supports a BGP black hole community from their customers, .e.g., 3356:666 ? I spoke with someone in their NOC but they lacked clue.

Thanks,
