Which of the following statements about Stub areas is false?
A Stub area is a type of area in OSPF (Open Shortest Path First) that restricts certain types of LSAs (Link-State Advertisements) to reduce the amount of routing information that must be processed. A Totally Stubby area is a more restrictive type of Stub area that does not allow summary LSAs (Type 3) except for a default route. However, not every Stub area can be configured as a Totally Stubby area; this is dependent on the network configuration and design. Therefore, the statement that any Stub area can be configured as a Totally Stubby area is false.
but totally stubby cannot contain LSA type 3...
they can contain one LSA T3 - default route. Maybe this is all about.
"The ABR of a totally stubby area disables origination of summary LSAs into this area, but still accepts summary LSAs from OSPF neighbors and floods them to other neighbors. " REF: http://docs.ruckuswireless.com/fastiron/08.0.60/fastiron-08060-l3guide/GUID-C466CC1E-F782-48EE-95C0-A180BFB91E5D.html
