Jon,
the easiest way (if you have enough routers in the lab)
is to use ping. On one router, specify
"ip igmp join-group 224.a.b.c", and then ping that group
from some other router:
ping 224.a.b.c
For example, test from my lab:
R1#ping 234.1.1.1
Type escape sequence to abort.
Sending 1, 100-byte ICMP Echos to 234.1.1.1, timeout is 2 seconds:
Reply to request 0 from 101.1.1.6, 52 ms
Reply to request 0 from 101.1.1.6, 80 ms
Reply to request 0 from 101.1.1.6, 68 ms
R1#
There are 3 paths to the multicast listener, so there are
3 responses (although only one icmp query will reach destination,
3 unicast packets are sent back).
