No, actually Mikrotik uses the *lowest* MAC address of all the ports belonging to the bridge.
The problem this causes is that if the bridge is one that has dynamic membership (PPTP, WDS, etc.), the bridge's MAC can change in mid-flight. > On Oct 8, 2015, at 6:07 PM, Josh Luthman <j...@imaginenetworksllc.com> wrote: > > Mikrotik uses the MAC of the first interface added to it, I believe.
