IGRP Issue

I have this problem:

R4's loopback address is running EIGRP.

R4's Serial 1/0 interface's address is running OSPF.

Mutual redistribution is also configured on R4.

R2 S0/0 connected to R4 through FR with OSPF Routing Protocol. Due to redistribtution on R4, I am able to see route on R2. Everthing is fine at that point. (Multipoint Frame Relay)

R2 S1/0 is connected to R3 S0/0 170.100.23/24 (Point-to-Point FR) running IGRP.

Mutual Redistribution is configured on R2 as well. Obviously I am not able to see the route from R4 into R3 routing table due to the classful nature of IGRP protocol.

The only work around I could have done is to summarize route on R4.

Here is what I did.

R4's S1/0

ip summary-address eigrp 1 I expected to see the route on R2's routing table so then it would redistribute that route to IGRP and then R3 would be able to see

this route, but didn't work. Somehow R2's is still getting the route.

Am I doing something wrong?



Re: IGRP Issue

the is more specific , this is the reason it is being put in the routing table. you may want to use a route-map with your redistribution that denies the /29 ip from being redistributed

Re: IGRP Issue

You got me wrong. I don't want to deny network. I want that network to be seen by R3. Since R3 is running IGRP it can't see network beyond /24 bit masks.

What would be the work around that is what my question was?


Re: IGRP Issue is running EIGRP. So there is no use of giving an "ip summary-address eigrp " command on the serial interface s1/0 of R4, (since this interface is running OSPF)....

You need to summarize the route via OSPF.

On R4, under OSPFgive a "summary-address" so that the redistributed route will appear as on R2.

Hope that helps@!
