R1 (с которого был снят дебаг, приложенный выше) - это центральный роутер ЛВС.
R2, R3 и R4 - граничные маршрутизаторы - серийниками смотрят в сторону удаленного объекта.
Каждый из 4-х роутеров одним эзернет портом сидит в общем влане, на каждом роутере поднят OSPF с одинаковыми area-id и анонсируемыми подсетями.
Ниже привожу дебаг OSPF RIB с R3 и R4 (метрика редистрибуции статических маршрутов настроена соответственно 50 и 100) при отключенном серийнике на R2:
