are operational and have appropriate IP address 

● 

show ip route: Checks to make sure that the dynamic routing protocol (OSPF) has populated routing 
entries learned through the routing process; the OSPF entries start with “o” in the routing table 

● 

Show ip ospf database: To check the status of OSPF protocol related information 

●
