Community range to match on import filter.

Hi there, just wondering how to migrate to Bird configuration this entry from another RR: “regex 65000:50[0-9][0-9]” applied to a BGP import route-map on community match. Tried on Bird: “if ([(65000,5000..5099)]) ~ bgp_community then “action" After that, no prefixes have been imported with those communities. Any idea if it should work or I’ve missed something? Thanks in advance. Regards, Jorge.
