Configuration Information

To view the OSPF configuration:

tnsr(config)# show route dynamic ospf config
interface GigabitEthernet3/0/0
    ip ospf area 0.0.0.0
exit
interface TenGigabitEthernet6/0/0
    ip ospf area 0.0.0.0
    ip ospf cost 10
exit
router ospf
    ospf router-id 10.2.0.1
    passive-interface GigabitEthernet3/0/0
