tnOspfMultiAreaConfigType

Specifies an OSPF area type:
normal areas are defined as areas that can
  accept intra-area, inter-area and external
  routes.
stub areas do not accept routes belonging to
  external autonomous systems (AS); however,
  these areas have inter-area and intra-area
  routes.  This reduces the size of the routing
  databases for the area's internal routers.
  Routers in the stub area also contain a
  default route which is advertised to the
  area by the Area Border Router (ABR).
totallyStub areas do not allow routes other
  than intra-area and the default route to be
  propagated within the area.  This further
  reduces the size of the routing databases
  for the area's internal routers.  The ABR
  advertises a default route into the area
  and all the routers belonging to this area
  use the default route to send any traffic
  outside the area.
nssa (Not So Stub Areas) can import AS external
  routes from within the area and send them to
  other areas, but cannot receive AS external
  routes from other areas.  Inter-area and
  intra-area routes are allowed along with a
  default route which is advertised to the
  area by the ABR.
nssaTotallyStub areas are similar to nssa
  with the added restriction that inter-area
  routes are not allowed.
