Class CIM_OSPFAreaConfiguration
extends CIM_LogicalElement

Each OSPF router has an association to one or more OSPF areas. Into these areas, a router advertises summaries filtered by specific address ranges. This would natively be modeled as a ternary association (router/OSPFService to OSPFArea to RangeOfIPAddresses), which is problematic in some implementations. To get around this issue, the OSPFAreaConfiguration class is defined to act as a focal point to bring together the router (indicated as a ComputerSystem with an instance of OSPFService, associated to the AreaConfiguration using OSPFServiceConfiguration), the area (indicated as an OSPFArea, associated to the AreaConfiguration using AreaOfConfiguration) and the address ranges for advertising (indicated as instances of RangeOfIPAddresses, associated to the AreaConfiguration using RangesOfConfiguration). There would be an instance of OSPFAreaConfiguration for each connected area of a router/OSPFService. When network administrators want to control the advertisements of OSPF routers by filters, they first define the relevant ranges. In order for a router to handle a range, an instance of RangeOfIPAddresses MUST be associated to the relevant OSPFAreaConfiguration (using the relationship, RangesOf Configuration). The association between the range and area configuration contains a property defining the handling (EnableAdvertise) to allow or disallow advertisements in the range. Notes: - Because RangeOfIPAddresses is scoped by a System (via the HostedCollection association), an instance of RangeOfIPAddresses would be associated to an OSPFArea, satisfying this semantic. - This class is inherited from LogicalElement, because a suitable subclass 'lower' in the inheritance hiearchy does not exist.

InstanceIDstring
DescriptionstringWithin the scope of the instantiating Namespace, InstanceID opaquely and uniquely identifies an instance of this class. In order to ensure uniqueness within the NameSpace, the value of InstanceID SHOULD be constructed using the following 'preferred' algorithm: <OrgID>:<OSPFService ID><Area Configuration ID> where: <OrgID> and the remainder of the InstanceID are separated by a colon ':', and where <OrgID> MUST include a copyrighted, trademarked or otherwise unique name that is owned by the business entity creating/defining the InstanceID, or is a registered ID that is assigned to the business entity by a recognized global authority. (This is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness <OrgID> MUST NOT contain a colon (':'). When using this algorithm, the first colon to appear in InstanceID MUST appear between <OrgID> and the <OSPFService ID>. For DMTF defined instances, the 'preferred' algorithm MUST be used, and the <OrgID> set to 'CIM'. <OSPFService ID> and <Area Configuration ID> MUST specify vendor-unique identifiers for the OSPFService and AreaConfiguration.
