Hi,
Could someone explain me difference between stub and totally stubby
areas ? I know that totally stubby area don't accept LSA type 3, 4 and 5
and stub area don't accept only 3 and for both only way out is default
route. But what is real result of that configuration. And how it connect
with redistributon of routes between OSPF and other routing protocols ?
Thanks,

You are close.  A totally stubby are won't accept LSA type 3, 4 and 5
so the only way out is a default route, just as you said.  A stub area,
however, does accept LSA type 3 so routing WITHIN OSPF network occurs
normally but will use a default route for EXTERNAL locations.

Not-so-stubby areas use LSA type 7 to redistribute external routes into
the area.
