I think you need summary address for same subnet because IGRP don't
understand VLSM so before you redist from OSPF to IGRP make sure all route
in ospf database got same subnet as igrp domain.
hope is help.

> เรื่อง: Losing routes when OSPF red into IGRP
>
> Hello,
>
> When I red OSPF routes into IGRP I am losing some
> routes.
>
> Example:
>
> OSPF clouds -- R1 --- IGRP ----- R2
>
> R1 has these routes in its OSPF database & Routing
> table. R1 can ping all these addresses.
> C 1.1.1.1 /24
> E2 2.2.2.2 /30
> E2 3.3.3.3 /24
> C 4.4.4.4 /24
> O 5.5.5.5 /24
> O 6.6.6.6 /30
>
> BUT R2 will not see 3.3.3.3 or 6.6.6.6. Where do
> these go? The routes being lost are not all subnetted,
> nor are they External OSPF routes.
>
> Sample configs:
> router ospf 1
> network 1.1.1.1 0.0.0.0 area 0
> red igrp 4 subnets metric 500 route-map IGRP2OSPF
>
> router igrp 4
> network 4.0.0.0
> red ospf 1 match e i metric 1500 100 255 1 1500
>
> Is there a debug to see the routes being redistributed
> and/or routes rejected for redistribution?
>
> FYI, R1 has a Frame connection with Multipoint subint.
> and networks 3, 5, & 6 can be routed 2 different ways.
> Does OSPF have a problem with this?
