vrIpOspfAreaAreaSummary 1.3.6.1.4.1.562.2.4.1.100.6.7.2.10.1.3

This variable controls the import of summary LSAs into stub areas. If it is noAreaSummary, the router will neither originate nor propagate summary LSAs into the stub areas. It will rely entirely on its default route. If it is sendAreaSummary, the router will both summarize and propagate summary LSAs.
