(config)#commit | Commit the candidate configuration to the running configuration |
(config)#exit | Exit configure mode |
Logging to a File

#debug ospf all | This enables the debugging on OSPF |
#configure terminal | Enter configure mode |
(config)#router ospf 1 | Enable OSPF process 1 |
(config-router)#exit | Exit router mode |
(config)#feature rsyslog | Enable feature on default or management VRF. By default this feature runs on the management VRF. |
