Stub Areas

OSPFv3 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 OSPFv3 routers. To configure an OSPFv3 area as a stub area, use the following command:
