What we usually do when we have a set of mixed nets is something like this: eth: 10.100.0.0/16 IB: 10.200.0.0/16 this allows us to keep the traffic easily and obviously separate, and not set up strange routing bits. -- Joseph Landman, Ph.D Founder and CEO Scalable Informatics Inc. email: landman-nyOC7EYE20mM0MU9lROt9DlRY1/6cnIP@public.gmane.org web : http://scalableinformatics.com http://scalableinformatics.com/sicluster phone: +1 734 786 8423 x121 fax : +1 866 888 3112 cell : +1 734 612 4615 -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
