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?
