OSPF VRF router configuration mode
Use this command to disable or re-enable the logging of specific events related to OSPFv2. If this command is not enabled only OSPFv2 messages indicating possible system errors are logged.
A limitation with the dr-only sub-option is that when a DR/BDR election is underway, OSPF neighbor state changes pertaining to non-DR/BDR routers are not logged. Logging resumes once a DR is elected on that network.
The no form of this command restores the default.
The following example enables the logging of all OSPFv2-related syslog events.
device# configure terminal device(config)# router ospf device(config-router-ospf-vrf-default-vrf)# log all
