4.4.4.2 Network Area

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.
Following is OSPF area configuration table. It is used to specify the OSPF enabled interface(s). When OSPF is enabled on the
specific interface(s), the router can provide the network information to the other OSPF routers via those interfaces. The screen
in Figure 4-4-4-2 appears.
