# Class CIM_OSPFArea
extends CIM_RoutingProtocolDomain

This class represents an OSPF area. The definition of an OSPF area from RFC2328, is 'OSPF allows sets of networks to be grouped together. Such a grouping is called an area. The topology of an area is hidden from the rest of the Autonomous System. This information hiding enables a significant reduction in routing traffic. Also, routing within the area is determined only by the area's own topology, lending the area protection from bad routing data.' This class has a 'Type' propery, which distinguishes between the different area types. This approach was chosen, because it provides a simpler way to indicate the type of an area, and additional subclassing is not needed at this time.
