AREA STUB

area stub
Overview This command defines an OSPF area as a stub area. By default, no stub area is
defined.
Use this command when routers in the area do not require learning about
summary LSAs from other areas. You can define the area as a totally stubby area by
configuring the Area Border Router of that area using the area stub no-summary
command.
There are two stub area router configuration commands: the area stub and area
default-cost commands. In all routers attached to the stub area, configure the
area by using the area stub command. For an area border router (ABR) attached to
the stub area, also use the area default-cost command.
The no variant of this command removes this definition.
