Illustratively, based on its name and AreaID syntax (the source DESCRIPTION is empty), this read-create value identifies the OSPF area ID a row of the multi-area configuration table pertains to. This is the key index letting an admin configure area-specific OSPF settings, like area type, opaque LSA handling, and default cost, for each distinct OSPF area the device participates in. As an illustrative example, a row with tnOspfMultiAreaId set to 0.0.0.1 would hold configuration specific to OSPF area 1.
