For the ospf/27 at area 0, area 0 range command at R2 will get /24 adverise to
area 1.
The main problem here is router R1 (igrp/24, ospf/29), a ospf area 1 router. Th
ere are several ways
to get /29 into /24.
I know any of the following will works:-
1. OSPF
=======
At R1, create a new ospf process(ospf_2),redsitribute the orginal ospf(subnets)
into ospf_2, address summary at ospf_2 on those non /24 into /24. At Igrp, red
istribute ispf_2 into
igrp.
2. IGRP
========
Since R1 need to advertise /29 as /24 to R0, two possible way:-
2.1 tunnel interface betw R0 and R1 with /29 network.
2.2 At R1 interface that connect to R0, create a secondary ip address with /29,
disable SP,
you will see that the /29 will advertise to R0, R0 will just treat it as a
/24..
eg
R1# interface xx ( connect to R0)
ip add 140.1.56.1 255.255.255.0
ip add 140.1.56.11 255.255.255.248 secondary
no ip sp
You may has to do filtering at this interface to re-enable the SP function.
Do a debug ip igrp tr to verify...

Hi Bob, i already has tried this, but it dont works properly. I think is becaus
e the R1 has in you table the /29 network directly connected, and the /27 is in
backbone area.
I tried also redistribute connected in R1 (only the /29) and make a summary-add
ress, this works fine.
For the /27 i did the same thing, but, in the R3 router.
I dont know if this is the better sollution, but is the unique that works.
let me know what you think..
thanks a lot again,
alex

Alex,
Try the following on R2:
area 1 range 140.10.200.0 255.255.255.0
area 0 range140.1.20.0 255.255.255.0
On R1, redistribute ospf into igrp. This works for me with a very similar set
up. Should see 140.10.200.0/24 and 140.1.20.0/24 on R1 and R0.
-Bob
