John, You can look into using Multicast Routing Monitor (MRM). Here is a working config.
R5 ip mrm manager myTest manager Ethernet 0/0 group 226.2.3.4 senders 1 receivers 2 sender-list 1 ! access-list 1 permit 161.1.45.4 access-list 2 permit 161.1.127.1 R4 interface Ethernet0/0 ip address 161.1.45.4 255.255.255.0 ip mrm test-sender R1 interface FastEthernet0/0 ip address 161.1.127.1 255.255.255.252 ip mrm test-receiver R5 mrm myTest start Basically you configure a manager, multicast test sender, and multicast test receiver. In this case R5 is the manager. R4 is the multicast sender and R1 is the multicast receiver. Look at some of the "show ip mrm" commands to see the results. This can also be used in the real world to monitor a real multicast stream. The config is essentially the same except the multicast test sender isn't needed.

I receive response to only the first multicast packet. Can some one give me a solution for this?
