Ospf Area Configuration - Planet Networking & Communication WGS3-2620 User Manual

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.
