area stub
Use this command to define an area as a stub area. There are two stub area router configuration commands: the stub and default-cost commands. In all routers attached to the stub area, configure the area by using the stub option of the area command. For an area border router (ABR) attached to the stub area, use the area default-cost command.
Use the no-summary parameter with this command to define a totally stubby area. Define an area as a totally stubby area when routers in the area do not need to learn about summary LSAs from other areas.
Use the no form of this command to disable this function.
