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 you can either use the
default settings of parameters such as the hello interval, LSA delay timer, and SPF calculation interval, or
configure those parameters as needed. OSPF routers should be configured on an area basis. Wrong
configurations might cause communication failures, routing information blocks, and routing loops.
Complete the following tasks to configure OSPF:
