OSPF (Open Shortest Path First) allows certain areas to be configured as stub areas. A stub area is connected to only one other area. The area that connects to a stub area can be the backbone area. External route information is not distributed into stub areas. Stub areas are used to reduce memory consumption and computational requirements on OSPF routers.
Use the following command to configure an OSPF area as a stub area:
configure ospf area area-identifier stub [summary | nosummary] stub-default-cost cost
