OSPF-area-mode
The following table summarizes OSPF area mode configuration commands.
area-type
Configures a particular OSPF area as STUB, Totally STUB, NSSA or Totally NSSA
Areas can defined as:
•
stub area - Is an area that does not receive route advertisements external to the autonomous
system (AS), and routing from within the area is based entirely on a default route.
•
totally-stub - Is an area that does not allow summary routes and external routes. A default route
is the only way to route traffic outside of the area. When there is only one route out of the area,
fewer routing decisions are needed, lowering system resource utilization.
•
non-stub - Is an area that imports autonomous system external routes and forwards to other
areas. However. it still cannot receive external routes from other areas.
•
nssa - A Not-So-Stubby Area (NSSA) is an extension of a stub that allows the injection of limited
external routes into a stub area. If selecting NSSA, no external routes, except a default route,
enter the area.
•
totally-nssa - Is a NSSA using 3 and 4 summary routes are not flooded into this type of area. It
is also possible to declare an area both totally stubby and not-so-stubby, which means that the
area will receive only the default route from area 0.0.0.0, but can also contain an Autonomous
System Boundary Router (ASBR) that accepts external routing information and injects it into
the local area, and from the local area into area 0.0.0.0.
