OSPF Area Settings

This window is used to configure the OSPF Area settings for the Switch. OSPF allows collections of contiguous
networks and hosts to be grouped together. Such a group, together with the routers having interfaces to any one of
the included networks, is called an area.

Description
Click the radio buttons to enable or disable the OSPF global state.
A 32-bit number (in the same format as an IP address - xxx.xxx.xxx.xxx) that uniquely
identifies the Switch in the OSPF domain. It is common to assign the highest IP
address assigned to the Switch (router).
Display the OSPF Route ID currently in use by the Switch. This Route ID is displayed
as a convenience to the user when changing the Switch's OSPF Route ID.

Description
A 32-bit number in the form of an IP address (xxx.xxx.xxx.xxx) that uniquely identifies
the OSPF area in the OSPF domain.
OSPF area operation Normal, Stub, or NSSA. In some Autonomous Systems, the
majority of the topological database may consist of AS external advertisements. An
OSPF AS external advertisement is usually flooded throughout the entire AS.
However, OSPF allows certain areas to be configured as "stub areas". AS external
advertisements are not flooded into or throughout stub areas. Routing to AS external
destinations in these areas is based on a (per-area) default only. This reduces the
topological database size, and therefore the memory requirements, for a stub area's
internal routers.
