OOPS. You're right of course. I was thinking about multiple Ethernet interfaces on DIFFERENT LANs. (Not different segments bridged, but not connected at L2, only at L3.) paul On Aug 28, 2012, at 7:44 PM, Johnny Billquist wrote: On 2012-08-28 17:58, Paul_Koning at Dell.com wrote: Maybe the thing to do is to turn on both interfaces -- that will give you a dual-link end node, which is something DECnet handles just fine. In fact, I've always argued that DECnet handles multiple connections to the same LAN much better than IP ever did, mostly because it addresses nodes rather than networks or interfaces. Uh... I would argue that that would be a very bad thing, as it means you'll have two interfaces with the same mac address... Sitting on the same network. I'm pretty sure I even have seen some DECnet documentation that just says "not supported", or even stronger words...
