To check OSPF routing tables, follow these steps:
1. Log in to the router or switch using a terminal emulator such as PuTTY or HyperTerminal.
1. Enter the privileged EXEC mode by typing “enable” and providing the enable password.
1. Enter the global configuration mode by typing “configure terminal.”
1. Type “router ospf” to enter OSPF configuration mode.
1. Use the “show ip route” command to display the OSPF routing table for the router.
1. You can also use the “show ip ospf database” command to display detailed information about the OSPF database for the router.
1. Review the output to see the OSPF routes in the routing table and verify that the network routes are correct.
1. You can also use the “ping” command to test connectivity to the OSPF networks to verify that the routing is working properly.
