Gabriel,
The area range only creates summary of LSA type 3. It doesn't summarize the
LSA type 5.
Area range is a method of "OSPF ABR Type 3 LSA Filtering"
(http://www.cisco.com/en/US/docs/ios/12_2t/12_2t4/feature/guide/ftabrt3f.htm
l#wp1033637)
Summarization in OSPF is possible in 2 ways :
1) On ABR using area range to summarize a summary route (LSA3)
2) On ASBR using summary-address to summarize redistributed routes inside
the ospf.

Hi Alan,
You can try to configure "area range" command on ABR with the "advertise"
keyword.
But you must configure on ABR of the area where the route is being
originated.
