Dear All,

I have trouble to establish ospf on BIRD 1.6.3 using FreeBSD 11 amd64, here is my topology and BIRD configuration:

router-a ------ router-b (directly connected use cat6)

router-a: 10.22.40.17/30

router-b: 10.22.40.18/30

bird.conf in router-a

        router id 10.5.16.1;

        debug all;

        import filter ospf_in_routerb;

        export filter ospf_out_routerb;

        tick 2;

        area 0 {

           interface "bge0" {

                stub;

                cost 5;

                hello 10; retransmit 2; wait 10; dead 40;

                type pointopoint;

                };

           networks {

                103.22.40.16/30;

                };

           interface "*" {

                cost 1000;

                stub;

                };

        };

}

bird.conf in routerb

        router id 10.5.16.2;

        debug all;

        import filter ospf_in_routera;

        export filter ospf_out_routera;

        tick 2;

        area 0 {

           interface "bge0" {

                stub;

                cost 5;

                hello 10; retransmit 2; wait 10; dead 40;

                type pointopoint;

                };

           networks {

                103.22.40.16/30;

                };

           interface "*" {

                cost 1000;

                stub;

                };

        };

}

I found the following error message from bird.log:

Why ospf neighbor can't established?

I'm new to ospf and really need help.

Thank you
