I don't think it is automatic although that might be the default config. Also, using IP multicast (via Sean's multicast code) likely causes IGMP to be used so the routers know the IPmc groups being created/joined/left. </hnr> > BTW, as I mentioned, this can be solved on the client side equally as > well as the SM side. How? <hnr> The client side can do a full join with all the SA required characteristics (called components in IB). There are downsides to both approaches: configuration (SM side) versus first joiner node characteristics are the ones enforced for the group which may not be the desired result. </hnr> _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
