MGID 0xff12401bffff0000 : 0x0000000000000016 corresponds to 224.0.0.22 (IGMP). Only Version 3 Reports are sent with an IP destination address of 224.0.0.22, to which all IGMPv3-capable multicast routers listen. The OpenIB stack is joining this group (as it is a end node) rather than attempting to creating this group (hence the component masks). It is joining as a full rather than send only member due to a limitation with some SMs not supporting send only (or non member) joins. Even if that were supported by the SM, if the group were not created first, the send only join would fail. It makes no sense to send when no one is listening so the fact that it does not join is a benign error (ignore the message). The code retries on the next send to this group anyhow. It takes a multicast router which would be listening to IGMP to create the group. Do you have one configured on your subnet ? -- 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
