There are no broadcast addresses in IPv6, their function being superseded by multicast addresses. Neighbor Solicitation messages are multicast to the solicited-node multicast address of the target address. So I don't think there is a "master" IPv6 group. The IPoIB I-D does say that all group parameters should come from the broadcast group. But that's an IPv4 group so I'm not sure about IPv6 as a node could have an IPv6 interface but no IPv4 interface. -- 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
