So you need to get /23 routes in R2 to send to R1 via IGRP. On R3 you
should put area range command(s) to summarize the /24 and /25 into the
appropriate /23. On R2 you should also put an area range command(s) to
summarize the /24 and /26 into the appropriate /23 for R2.
Let me know if this works for you.

Let me elaborate more.
R1--R2--R3--R4
R1 connectedto R2 and running IGRP. (subnet mask /23)
R2 connected to R3 is running OSPF with Area 0. (subnet masks /23, /24,
/26)
R3 connected to R4 is runing OSPF but Area 1. (subnet masks /23, /24,
/25)
I know R3 is ABR we can use "range" to summarize to /23 and then
distribute to R2.
My question is how R2 can summarize /24 and /26 to /23 such R1 can
receive route from R2. I can use "summarary-address" on OSPF in R2 to
generate routes to "NULL" with subnet mask /23 in routing table on IOS
12.0 but it doesn't work on 12.1.
Pls advise.
