There are two configuration commands for stub area: stub and default-cost If you want to configure one area as the stub area, you must configure all routers in the area by the stub command.
The default-cost command takes effect only when it is configured on an ABR. The command is used to specify the cost of the default summary route transmitted by the ABR to the stub area.
On an ABR, you can configure the no-summary of the stub command to prevent Type-3 LSA from entering the stub area that the ABR connects to.
The backbone Area 0 cannot be configured as a stub area.
