according to http://blog.ine.com/2009/08/17/ospf-rou ... mystified/ , for OSPF area borders, the ABR should redistribute the routing table (filtered) from the backbone area into the other areas.
On my setup, the ABR would redistribute the whole OSPF Routing Database without filtering into the adjacent non-backbone area.
