The Area Aggregate Table acts as an adjunct to the Area Table. It describes those address aggregates that are configured to be propagated from an area.
Its purpose is to reduce the amount of information that is known beyond an Area's borders.
It contains a set of IP address ranges specified by an IP address/IP network mask pair.
For example, a class B address range of X.X.X.X with a network mask of 255.255.0.0 includes all IP addresses from X.X.0.0 to X.X.255.255.
Note that if ranges are configured such that one range subsumes another range (e.g., 10.0.0.0 mask 255.0.0.0 and 10.1.0.0 mask 255.255.0.0), the most specific match is the preferred one.
The indexes of the table are ospfAreaAggregateAreaID, ospfAreaAggregateLsdbType, ospfAreaAggregateNet, ospfAreaAggregateMask.

INTEGER{active(1),notInService(2),notReady(3),createAndGo(4),createAndWait(5),destroy(6)} |
read-create |
This object permits management of the table by facilitating actions such as row creation, construction, and destruction. The value of this object has no effect on whether other objects in this conceptual row can be modified. |
The actually supported access is read-only. |
|

ospfAreaAggregateEffect |
INTEGER{advertiseMatching(1),doNotAdvertiseMatching(2)} |
read-create |
Subnets subsumed by ranges either trigger the advertisement of the indicated aggregate (advertiseMatching) or result in the subnet's not being advertised at all outside the area. |
The actually supported access is read-only. |
|
