OSPF configuration task list

Make a proper plan before configuring OSPF.

To run OSPF in a routing domain, you must first enable OSPF on the routers. Then use the default settings of parameters such as the hello interval, LSA delay timer, and SPF calculation interval. You can also configure them as needed. OSPF routers should be configured on an area basis. Wrong configurations may cause communication failures, routing information blocks, and routing loops.

Complete the following tasks to configure OSPF:
