We are configuring an OSPF totally NSSA area with two ABR. When one ABR loses connectivity with backbone area (each ABR only has one link to backbone area) , NSSA area internal routers learn only one default route. But I'm noticing when we connect again that ABR to backbone area, it starts to inject default route into NSSA area before reaching OSPF full state in backbone area. Therefore ip flows load balanced to this ABR from inside of NSSA area will fail until this ABR reach OSPF full state.
Is there anyway to workaround this problem, delaying route default injection until ABR gets full state?
