Which type of area best describes a stub area?
- a small area
- an area with only one router
- an area with no externally learned routes
- an area that is discontiguous from the backbone area
Explanation: Stub areas reduce the size of the routing table by preventing external routes (type 5 LSAs) and ASBR summary routes (type 4 LSAs) from entering the area. The ABR automatically generates a default route for all the routers in the stub area so each router can reach other areas. The ABR has the external and summary routes in its own routing table.
