Re: [OSL | CCIE_RS] Stub Areas

Stub area = when you don't need to use this area as a transit area,
when there's only one way out of this area

Totally stub area= same as stub area but ONLY want to use a default
route to get out of the area

Totally NSSA = same as totally stub area in that you use a single
default route to get out BUT you can also have a router in this area
redistributing from another protocol into OSPF in this area

NSSA= same as above but with specific routes advertised from the exit
router of this area.

Subtle but important differences...
