So your picture is a little hard to read.
Is R3 doing OSPF and IGRP and redistribution between?
R4 doing IGRP and RIP?
Where is the ip default-network defined? That is what you are using?
Seems you are defining the "ip default-network" on R4. So the "ip
default-network" should be on R3 if you want to reach the networks
on OSPF. Or else you need to make it so that all the OSPF routes get
redistributed into IGRP. If you have OSPF routes that are not the same
mask as the network between R3 and R4 they will not get sent to R4.
Actually I should say if the network mask is larger they will not get sent.
For example. If the OSPF network is /25 and the R3 to R4 network is /24
this route will not get sent to R4. You will need to summarize on the OSPF
network this route to be a /24.
The easiest way to get reachable to the OSPF networks is to use
"ip default-network".
Maybe if you could redraw and document each piece it would be
easier to understand.
