Kamal,
I have done some quick labbing around your example and it seems to work
fine for me.
R2 e0/0 - e0/0 R1 S0/0 -FR- S0/0 R3 e0/0 -
R1 marks all traffic from R2 with ip dscp af42 inbound on e0/0 interface
and marks traffic that matches your class-map with fr-de bit outbound on
s0/0.
Now if we have a small eigrp routing domain between R1 R2 and R3 and
ping R3 e0/0 from R2 (via R1), that ICMP traffic is marked alright with
ip dscp af42 first and then fr-de bit adds.
I used 2611 routers with c2600-j1s3-mz.123-20 on board. You most
probably missing something in your config...
