In Cisco Packet Tracer, OSPF (Open Shortest Path First) testing is the process of verifying that routers running the OSPF protocol have successfully formed neighbor relationships and are correctly exchanging routing information. After configuring OSPF on routers, testing ensures that the OSPF network is functioning as expected and that all routes are reachable.
Testing typically involves:
Checking OSPF Neighbors: Using commands like show ip ospf neighbor to confirm adjacency between routers.
Verifying Routing Tables: Using show ip route to ensure OSPF-learned routes appear with the “O” code.
Pinging Across Networks: Sending ICMP ping requests between end devices in different OSPF areas to verify end-to-end connectivity.
Monitoring Convergence: Observing how quickly OSPF updates routes after changes in the network topology.
This process confirms that the OSPF configuration is correct, the routers are advertising and learning routes properly, and that inter-network communication is possible within the simulated environment.
