I have this scenerios: R4's loopback address is 170.100.40.4/29 running EIGRP.R4's Serial 1/0 interface's address is 170.100.124.4/24 running OSPF. Mutual redistribution is also configured on R4. R2 S0/0 170.100.124.2/24is connected to R4 through FR with OSPF Routing Protocol. Due to redistribtution on R4,I am able to see 170.100.40.4/29 route on R2. Everthing is fine at that point. (Multipoint Frame Relay) R2 S1/0 170.100.23.2/24 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 170.100.40.4/29 from R4into R3 routing table due to the classful nature of IGRP protocol. The only work around I could have done in this scenrio to summarize route 170.100.40.4/29 on R4. Here is what I did. R4's S1/0 ip summary-address eigrp 1 170.100.40.0 255.255.255.0. I expected to see the route 170.100.40.0/24 onR2's routing table so then it would redistribute that route to IG RP and then R3 would be able to seethis route, but didn't work. Somehow R2's is still getting the 170.100.40.4/29 route. Am I doing something wrong? Regards, Teza
