Hello

Works for me, at least in some similar setups.

Could you check if it works for expressions like:

bird> show route all where (rt,65001,28773) ~ bgp_ext_community


Or (function in config file):

function test2(int peer_as)
{
 if (rt,65001,peer_as) ~ bgp_ext_community then {
     return true;
  }
  return false;
}

bird> show route all where test2(28773)
