So, we can already do stuff like this on a bgp filters, like this one on a
a bgp import:


        if (64511,11) ~ bgp_community then {

                gw = RTD_BLACKHOLE;
        }

..with choices of:

RTD_BLACKHOLE, RTD_UNREACHABLE or RTD_PROHIBIT



But I guess direct support would be good.



Cheers,
