Community range to match on import filter.

[Osmos City]

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.
