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?
