Combining routes in BIRD BGP export

[Dmitry S. Nikolaev]

Hi.

Yes, why not.

filter ospfOUT {
    if (source = RTS_STATIC) && (net = 1.2.3.0/24) then {
        accept "ospfOUT: Send our Aggregated pref ", net;
    }
    reject;
}

protocol ospf {
         ...skiped....
        area 0.0.0.0 {
               ...skiped....
        };
        import filter ospfIN;
        export filter ospfOUT;
}
