4.5.6.2.3.1 OSPF Area Configuration
OSPF protocol broadcast messages (i.e., Link State Advertisements) are restricted by area to limit their
impact on network performance. Before assigning an Area ID to a specific OSPF interface, you must first
specify the Area ID in this table. Each entry in this table identifies a logical group of OSPF routers that
actively exchange Link State Advertisements (LSAs) to ensure that they share an identical view of the
network topology. You can configure the area as a normal one which can send and receive external Link
State Advertisements (LSAs), a stubby area that cannot send or receive external LSAs, or a
not-so-stubby area (NSSA) that can import external route information into its area.
