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.

Subject: Pinging a Multicast address
Hi group,
I practicing multicast and I am trying to get the router below to send a
continuous multicast stream. I receive response to only the first
multicast
packet. Can some one give me a solution for this?
Thanks
