Re: RIP to OSPF redistribution

I have a similar question.
If R2 don't have some area about 140.100.2.0/24
I think R1 also don't have "140.100.2.0/24" route.
How can R1 have route of "140.100.2.0/24"

I'm sure this question has been asked a million times, but the archives
aren't giving me the answer I'm looking for. How do you summarize OSPF
type 3 LSAs into RIP when there is no ABR to summarize on?

R1-----(ospf)-----R2------(rip)------R3

R1 - R2 is subnet 140.100.1.0/30
R2 - R3 is subnet 140.100.2.0/24

How can R3 learn about 140.100.1.0/30 without using static routes?
There is no ABR to use "area range", and there is no inbound ASBR to use
ospf "summary-address", nor are these type 5/7 LSAs.

Answers I've heard so far are:

"use the ip summary-address rip" command on R2, but I tried that in the
lab and nothing happened. Maybe I was doing something wrong?

"use a default-network" on R2, and I have used this in a practice lab,
and it worked, but I'm worried that a real lab won't allow default
routes.

Any comments would be greatly appreciated.
