Questions on community handling

Hi all, I have a couple of basic questions regarding communities: - is the "interpret communities switch" command meant only for well-known communities or for any community sent to the RS? - how can I see from birdc if a member is sending a specific community to the RS? "sh route where ((<mycommunity>)) ~ bgp_community"? Thanks, Simone. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
