Which command displays information on each OSPF interface?

The command that displays information on each OSPF interface is indeed "get router info ospf interface." This command provides detailed information about all the interfaces that are participating in OSPF (Open Shortest Path First) routing on the device.

When executed, it shows parameters such as OSPF area, cost, state, and other relevant metrics for each interface configured for OSPF. This is valuable for network administrators as it helps in monitoring and troubleshooting OSPF routing configurations, ensuring that the interfaces are operating correctly and participating in the OSPF routing process as intended.

In contrast, while the other commands serve useful purposes, they do not focus specifically on the interface-level information. For instance, one command might provide an overview of the OSPF status for the entire router, while another might summarize OSPF neighbors or give a brief on the database. However, only the command that directly references "interface" gives the granular details specific to the interface configuration and its operational state within the OSPF context.
