But I'm disagreeing. There is a lot wrong with having the same address on multiple ports of a box, when those multiple ports share the same network. This is true both at layer 2 and at layer 3, right? There are work-arounds, such as ensuring only one port is active, e.g. via STP or whatever. The Sun scheme worked only under certain circumstances. It would violate standards in certain scenarios. > Having the same MAC address shared between two (or more) boxes *is* > wrong, standards-wise.
