I'll take a first crack and look at the code to see what I can determine. On the second issue, I partially understand what is going on: IPmc group changes need to be reported via IGMP so the IPmc router knows to prune the multicast tree, but... I don't understand why it joins here (and not earlier when a IPmc group is first joined by this node and second after the join is successful, I do not see any IGMP packet come out of the node (onto IB; maybe it is going out the ethernet instead). -- Hal _______________________________________________ openib-general mailing list [EMAIL PROTECTED] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
