Hi Keenan and Ondrej,

I already update the configuration as your advice but the still couldn't be established, here is the new configuration:

Router A


protocol ospf {
        router id 10.8.60.1;
        debug all;
        import filter ospf_in_routerb;
        export filter ospf_out_routerb;
        area 0 {
           interface "bge0" {
                cost 5;
                hello 10; retransmit 2; wait 10; dead 40;
                type broadcast;
                };
           interface "*" {
                cost 1000;
                stub;
                };
        };
}

Router B
protocol ospf {
        router id 10.8.60.2;
        debug all;
        import filter ospf_in_routera;
        export filter ospf_in_routera;
        area 0 {
           interface "bge0" {
                cost 5;
                hello 10; retransmit 2; wait 10; dead 40;
                };
           interface "*" {
                cost 1000;
                stub;
                };
        };
}


2016-12-31 10:44:51 <TRACE> ospf1: HELLO packet sent via bge0
2016-12-31 10:44:51 <ERR> ospf1: Socket error on bge0: Invalid argument

How to debug this instance in a deep level?

Thank you




Best regards,
David S.

Why tick 2?

There should not be 'stub' if the interface is supposed to be active.

'networks' is irrelevant unless you have multiple areas.

It is interesting what causes socket error if the interface is declared
to be stub.
