Can you explain why two clients share the same MAC address?

Duplicate mac addresses are not allowed on the same Layer2 network. One of them will need to change their mac address. If you backup 1 Mikrotik, the mac addresses of the interfaces are backed up too. If you restore that config to a different Mikrotik, the mac addresses are applied to the new device. So if you backup a config and apply it to many Mikrotiks, you have to reset the mac to default on the cloned Mikrotiks.
