HI

see:
http://www.cisco.com/en/US/tech/tk648/tk365/technologies_tech_note09186a0080094707.shtml

Haven't test this..but I think that prior to 12.1.3
"redi conn" whereby the connect routes are the same as
the "network xxx" would create lsa 5 on the asbr (r1)
so that when these lsa 5 reaches another abr (or get
summarized), they become summary lsa 4 and get
propagated..so it should work via intra/inter areas.

After 12.1.3, I think you would need the "area range"
(assuming that you are practicing redist btwn classful
and classless to rip or create a dummy area with a
loopback with an "area range" on the dummy area)
