area stub
Use the area stub command in Router OSPF Configuration mode to create a
stub area for the specified area ID. A stub area is characterized by the fact
that AS External LSAs are not propagated into the area. Removing AS
External LSAs and Summary LSAs can significantly reduce the link state
database of routers within the stub area. Use the no form of the command to
remove the stub area.
