RE: Problem with redistribution from OSPF to IGRP

Gustavo,

IGRP will not accept this route because it is a /32 not /24, which is what your IGRP link is. You can do two things to get IGRP to see this route. Since this route is an IA route you can do an "Area X range 133.10.5.0 255.255.255.0" on your ABR, or you can do an "ip ospf network point-to-point" on the loopback interface this route is originating from.

Either solution will work. Which on you use will depend on your requirements.

HTH,

Brent

Subject: Problem with redistribution from OSPF to IGRP
Hi guys,

I'm doing the test Skylabs(Dart) from Pratical studies.

The problem is the redistribution from OSPF to IGRP, I do not know what is
happening ...... already I tried of everything...

This is the configuration....

R1#router ospf 10
 router-id 133.10.1.1

          routing via 133.10.11.2, Serial0.2

I don't know why the route 192.168.1.0/24 is coming back and why the route
133.10.5.0/24 is not passing......

R2 (just IGRP) #show running
router igrp 10

Could someone tell me what I am doing wrong?

Thanks.

Gustavo,
