Hi,
I'm confused on the subject of totally stubby areas, and the command "area
default-cost". From what I'm reading, one of the qualifications of a totally
stubby area is that if multiple exits (ABRs) exist, routing to outside the
area does not have to take an optimal path. Does this mean that e
helps. I derived this information partly from Doyle's book on
TCP/IP Routing and the CCO.
Sincerely, Raul

Totally stubby is a cisco nob that takes the concept of a stub area a step further.
In a stub area, only LSA types 1 (router) 2 (network) and 3 ( summary) flow within the
area. Hence, no routing information concerning prefixes outside of the OSPF domain is
injected into the area. In a total

Raul, thanks for your reply,
"Routing to the outside world could take a sub-optimal path in reaching the
destination by going out of the area via an
exit point which is farther to the destination than other exit points"
Does this mean that cost metrics do not come into play within stub areas?

Bob,
I'll try to answer your first question below at the expense of possibly
clouding the issue:
*Question: Does this mean that each router within the area picks the
closest ABR as the gateway to everything outside the area,...
Well...Yes! OSPF first takes the "shortest path"
