Unfortunately static routes are not an option, I have now successfully
tried summarising from /24 OSPF domain to /22 IGRP domain by using OSPF
process 2 and redistributing OSPF 1 into it and OSPF 2 into IGRP having
declared summary addresses in OSPF 2 as suggested by many of you for
which I am very appreciative. But the other way around is not yet
solved. By the way, this scenario comes direct from Solie's unnamed lab
and his solution does not address this problem which makes me wonder how
his R4 had connectivity to the rest of his lab. I have seen another
posting for this problem but there were no responses.
Many thanks everybody for your help. I am sure solving this ongoing
problem is helpful to everyone.

Can you use a static route? and redistribute static?

Area 2 is ASBR, Area 0 only. 137.7.8.1/22 belongs to e0 which connects
to
R3 which is ABR, R3 is ABR with Area 0 and 10. I have tried the area
range
and summary addres on R3 without luck.
Thanks for your help.

R2 has the /22 network.
Is the network a loopback or is it actually adjoined to another router?
If it is adjoined to another router why type of OSPF router is it? ABR?
Area 0 only?
If it is an ABR try summarizing there.
Give us more of the config on R2.

Hi All,
I have read through the archives and attempted the most viable solution
without success. R4 runs IGRP on /24 mask adjoining R2 which runs IGRP
and
OSPF area 0. R2 has e0 as 137.7.8.1/22 - how to get this into IGRP? I
cannot
use area range or summary commands in area 0 so I create a second OSPF
process
- OSPF 2 - and redistribute OSPF proc 1 into OSPF 2 then use the summary
address - 137.7.8.0 255.255.255.0 without joy. If I add a 'red
connected sub'
command to OSPF proc 2 as well then I get a null0 summary to the subnet
on R2
and R4 sees it in IGRP but pings the null0. Any ideas? Thanks. I am
running
IOS 12.0(15).
