It is NOT a layer 3 device. It is layer 2. That's the best and only option if you want to not have a second interface board in the hosts.
When a packet comes in for an IB device, the gateway box puts the IP packet onto the required IB destination frame and sends it along. _______________________________________________ Tech mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
