Although there are 10 nodes having IP connectivity, only 5 of them are
subscribed to the group 239.192.0.1, all the 10 are configured to subscribe
for the group 239.192.0.1.
I have <debug ip igmp> & <terminal monitor> on my VTY line, but do not see
any logs from these hosts when they join/leave different groups.
any suggestion will be of great help...
