This was filling log, until that interface on other router was up again.

OSPF setup is quite simple, Bird is in default area 0.0.0.0, route
10.0.95.236 is on router in different area (totaly stub) for which router
172.31.1.13 is ABR.

Why is Bird repeatedly logging "LSA disappear" for same prefix? Could this
be disabled in some way? Or have I something wong in Bird config?

OSPF protocol config is realy simple:

protocol ospf ospfbackbone {
    import all;
    export filter doospf;
    area 0.0.0.0 {
        interface 172.31.1.0/24 {
                 cost 10;
                 hello 10;
                 retransmit 5;
                 priority 250;
                 dead 40;
                 type broadcast;
                 authentication cryptographic;
                 password "hidden";
              }; #int
    }; #area
}

Thanks for response.
