Hi Broadway,
Am not sure the ping (with source, size, ...etc) approach will work (u'r
sending unicast). Rate limit is based on (S, G).
A good reference on rate-limit:
ftp://ftpeng.cisco.com/ipmulticast/config-notes/multicast-rate-limit.txt
Start "deb ip packe" and let the interface join that group.
Also, the "show ip mroute int e0/0" shou;d show u if the rate-limit is
applied.
interface FastEthernet0/1
ip address 162.1.3.3 255.255.255.0
ip pim sparse-dense-mode
ip multicast rate-limit out group-list grp-224 100
ip igmp join-group 224.1.1.1
duplex auto
R3(config)#int f0/1
R3(config-if)#sh
R3(config-if)#no sh
R3(config-if)#end
