Rip v2 to OSPF Redistribution Problems

Tavis10284

Hello all.

I am trying to complete Phase 2 of the CCNA 4 WAN case study. I have the addressing correct according to what the instructor checked and when comparing to everyone else.

On phase 2, one of the bullets of items to complete is to Configure and redistribute RIP into the OSPF routing process.

After configuring all the routers (Limerick, Belfast, Cork, and Galway) with the appropriate routing protocols, IPs, etc, and then implementing the redistribute commands, I attempt to test the interfaces by pinging them using the IP address of each int.

I've found that I can get to all interfaces except the following:

When pinging from the Galway router to Limerick S0 (172.16.255.249)

from Galway to Belfast E0 (10.0.0.1)

from Galway to Befast S1 (172.16.255.250)

When pinging from the Limerick router to Galway E0 (172.16.4.1)

from Limerick to Galway S0 (172.16.255.245).

If you need any more information, I will be happy to give it. I found this PDF of the Case Study I am referring to.

I could not attach the Limerick config (3 max attachements) but it is below:

#Limerick:

en

config t

service timestamps debug uptime

service timestamps log uptime

no service password-encryption

hostname Limerick

enable secret xxx

ip subnet-zero

interface Ethernet0

no ip address

no ip directed-broadcast

router ospf 1

network 172.16.255.248 0.0.0.3 area 0

ip classless

transport input none

Also, when comparing results to others in the class, they are having the same issue as I am.

Thanks for any help that you may provide!

Hi,

You need to add the following to the Cork router:

router rip

redisribute ospf 1 metric 1

Hope that helps - pls rate the post if it does.

That worked very well. Thanks!

I've also learned that I could do an ip route 0.0.0.0 0.0.0.0 s0 on Galway and it would work also.

The default route would certainly have worked, at least in this scenario. But the redistribution of OSPF into RIP is a more elegant solution, I would like to think :-)
