OK, now maybe I'm missing something here. But an Ethernet address is used to identify a board. Arp binds it to an IP address. An IP address is bound to a network. So if you're on a different network, you get a different IP address. Why do you need the same Ethernet address? This is very different from having two boards on the same network, both with the same Ethernet address. As I observed earlier, that does make sense, but it's a hot standby situation. I can't see any point in arranging for both of them to accept or send data.
