You need to configure your loopback interface on R3 with the "ip ospf
network point-to-point" statement.

Subject: OSPF to IGRP Redistribution

Everyone,

I am working on a problem with three routers R3, R1, R4. R3 is advertising
his loopback address under OSPF with a network statement for area 0. R1 is
performing mutual redistribution between OSPF and IGRP. R1 route table shows
the loopback address with /32 mask. R4 does not learn about the loopback
address via redistribution. Why? Below are the configs

R3
router ospf 2001
 area 0 authentication message-digest
 network 155.100.34.0 0.0.0.255 area 0
 network 155.100.37.0 0.0.0.255 area 70
 network 155.100.38.0 0.0.0.255 area 70
 network 155.100.39.0 0.0.0.255 area 70
 network 155.100.123.1 0.0.0.0 area 0
