Technology Review
In order for OSPF to operate on an interface, the primary address for the interface must be included in the
network area command. Assigning an interface to an OSPF area is done using the network area
command. There is no limit to the number of network area commands used on a router. If the address
ranges defined for different areas overlap, the first area in the network area command list is used and all
other overlapping portions are disregarded. Try to avoid overlapping to avoid complications.
Usage Examples
In the following example, the OSPF routing process is enabled and two OSPF areas are defined:
(config)#router ospf
(config-ospf)#network 192.22.72.101 0.0.0.255 area 0
(config-ospf)#network 10.0.0.0 0.255.255.255 area 10.0.0.0
