What command is used to view the current OSPF routing table?

#show ip route
#display ip ospf route
#show ip ospf summary
#check route status

The correct answer is: #show ip route

The command used to view the current OSPF routing table is "show ip route." This command displays the entire routing table for the router, including the routes learned through various protocols, such as OSPF (Open Shortest Path First). When examining the output, OSPF routes are typically identified with the letter "O" next to the network prefixes. This allows network administrators to verify which OSPF routes are currently active and being used for packet forwarding. The output from this command is essential for troubleshooting and optimizing network performance, as it provides insights into the routing decisions being made within the OSPF-configured network. By understanding the routes OSPF has installed in the routing table, one can address issues related to connectivity, route redistribution, and overall OSPF configuration.
