Which command shows the current OSPF configuration on a device?

The command that shows the current OSPF configuration on a device is "show running-config." When this command is executed, it displays the entire active configuration of the device, including details about OSPF such as router IDs, network statements, area configurations, and any OSPF-specific settings that have been applied. This comprehensive view is vital for network administrators to verify and troubleshoot OSPF settings effectively.

While other commands like "show ip route" provide information about the routing table, including OSPF routes, they do not display configuration settings. The command "show ospf configuration" does not exist on Juniper devices in this context, making it irrelevant. Similarly, "get ospf status" is used for obtaining operational status and statistics about OSPF but does not reflect the configuration itself. Thus, "show running-config" is the most accurate command for retrieving the OSPF configuration on a device.
