In OSPF configuration mode on your ASBR, you can issue the command "default-information originate". As long as the ASBR has a default route in it's routing table, it will inject it into OSPF. Note that you cannot redistribute a 0/0 route into OSPF. You don't have to create static routes on your ABR's, as the Type5 LSA's will be propogated into your areas. If your areas are stub areas, then the ABR will block Type5 LSA's and inject it's own default into the area, such that routers in the area will know about all routes inside the AS, but will use the ABR as their default gateway, trusting that it will know how to route the packet accordingly to the ASBR. If your areas are totally-stub areas ( a cisco-only implementation ) then all Type3,4,5 LSA's are blocked and ONLY a default will be passed into the area, so the area would only have routes internal to the area and a default to get out of the area. Hope this helps...
