Steve,

If you want to use area range command, you need to put the LO0 in let's say
area 1, at that point you can use area range command and this should work
and will give you the /24.
Here is what you will see on R5

     138.20.0.0/24 is subnetted, 1 subnets
O IA 138.20.1.0 [110/65] via 63.101.250.1, 00:00:03, Serial1
     64.0.0.0/24 is subnetted, 1 subnets
C 64.101.250.0 is directly connected, Ethernet0
     63.0.0.0/24 is subnetted, 1 subnets
C 63.101.250.0 is directly connected, Serial1

Also here is what you should have on R6 after redistribuation....

I 138.20.0.0/16 [100/2100] via 64.101.250.1, 00:00:19, Ethernet0
     64.0.0.0/24 is subnetted, 1 subnets
C 64.101.250.0 is directly connected, Ethernet0

Thanks

Here's the scenario -

(loop0 138.20.1.1/28) r1 ----------fr ospf/24----------- r5--------eth igrp
/24 ----------r6

redistributing ospf into igrp and igrp into ospf.

Loop0 on r1 is /28

  router ospf 10
    network 138.20.1.0 0.0.0.15 area 0
    area 0 range 138.20.1.0 255.255.255.0

Yet r5 sees ospf network 138.20.1.1/32 and r6 doesn't see r1 loopback
(obviously)

Why can't r5 see network 138.20.1.0 as a /24? Appreciate your input.

Steve
