You cannot remove an OSPFv3 area directly. Only when you remove all configurations in area
view and all interfaces attached to the area become down, can the area be removed.
z
All the routers attached to a stub area must be configured with the stub command. The keyword
no-summary is only available on the ABR of the stub area.
z
If you use the stub command with the keyword no-summary on an ABR, the ABR advertises a
default route in an Inter-Area-Prefix-LSA into the stub area. No AS-external-LSA,
Inter-Area-Prefix-LSA or Inter-Area-Router-LSA is advertised in the area. The stub area of this kind
is also known as a totally stub area.
