How to set the protocol, Open Shortest Path First (OSPF)
Step 1: Enter privileged EXEC mode:
Router>enable password
Step 2: Enter the configure terminal command to enter global configuration mode.
Router#config terminal
Step 3: Enter the router ospf command and follow by the process-id.
Router(config)#router ospf process-id
Pick the process-id which is not being used. To determine what ids are being used, issue the show process command.
Router(config)#show process
Step 4: Add the network number, mask and area-id
Router(config-router)#network network-number mask area area-id
The network-number identifies the network using OSPF. The mask tells which bits to use from the network-number, and the area-id is used for determining areas in an OSPF configuration.
Example:
Router(config-router)#network 192.168.10.0 255.255.255.0 area 0.0.0.0
