Certain areas can be defined as stub areas in OSPF. This prevents external networks, e.g.
those propagated from other protocols by redistribution in OSPF, being propagated into the
stub area. Externally routing of such areas is propagated with a default route. The configur-
ation of a stub area reduces the database size in the area and reduces the amount of stor-
age space needed on the gateways incorporated in the area.
15.2.1 Areas
OSPF areas must be defined before the gateway interface can be assigned to an area.
A list of all configured OSPF areas is displayed in the Routing Protocols+OSPF+Areas
menu.
