Ah, sorry. This is on the zebra box:

Bird is 10.9.8.26 Zebra is 10.9.8.21 and Cisco is 1.9.8.1

I've tried both Zebra and Bird on Both machines, the results are
identical both from Zebra and Bird.

Oh and the Bird config is: 

protocol device {
#       #scan time 10;
}

protocol direct {
}

protocol kernel {
        import all;
        learn;
        export filter {
                print net;
                if scope = SCOPE_HOST then {
                #if net ~ 10.9.8.0/24 then {
                   reject;
                } else {
                   accept;
                }
        };
}

protocol ospf gaustad {
        #rfc1583compat yes;
        debug all;
        import all;
        export filter {
                ospf_metric1 = 100;
                accept;
        };
        area 0 {
                tick 8;
                interface "eth0" {
                        #hello 30;
                        retransmit 6;
                        cost 10;
                        #transit delay 5;
                        #dead count 5;
                        wait 50;
                        type broadcast;
                        authentication none;
                        password "pass";
                };
        };
}

The export filter on protocol kernel is an attempt to stop Bird from
accepting routes to directly conncted subnets. It doesn't seem to be
working.
