Type Define the area type by choosing one of the following:
•Normal – Make the area a standard OSPFv3 area. This option is
selected by default when you first create an area.
•NSSA – Make the area a “not-so-stubby area.” NSSAs accept Type
7 LSAs. When you choose this option, the Default Information
Originate options are enabled.

being flooded into the area by deselecting Allow sending summary
LSA into this area. You can also disable route redistribution by
deselecting Redistribute, and enabling Default information

3 and 4) from being flooded into the area by deselecting Allow
