As per RFC draft-ietf-pim-dm-new-v2-03.txt
Prune messages are sent towards the upstream
neighbor for S to indicate that traffic from S addressed to group G is
not desired. In the case of two downstream routers A and B, where A
wishes to continue receiving data and B does not, A will send a Join in
response to B's Prune to override the Prune. This is the only situation
in PIM-DM in which a Join message is used. Finally, a Graft message is
used to re-join a previously pruned branch to the delivery tree
Does it help? There is two times 'ip igmp join-group' in your emai. Do
you mean 'no ip igmp join-group' on the second time?

Assunto:R6 does not send prune message [7:65415]
Hi Group,
When i configured r6 with ip igmp join-group command it generated I graft
message to the ustream router, but it did not generat a prune message when
i
entered ip igmp join-group. Could some one just tell me why ?
BTW the network is runing dense mode multicast.
Thanks
John Tafasi
