Explanation:
To define a totally stub area, use the area area-id stub no-summarycommand on the ABR (in
OSPF router configuration) and thearea area-id stub on the totally stub router. The ABR will inject
a default route into the area so routers in this type of area only see routing information local to
their area, plus a default route pointing to the ABR, from which they can reach all other areas and
all other networks
