z 

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. 

 

You can configure a virtual link to maintain connectivity between a non-backbone area and the 

backbone, or in the backbone itself.  

Follow these steps to configure a virtual link:
