eoip tunnels and bridges mac addresses

RouterOS General
1

Hello,
I have RB750Gr3 (6.39.3) with these interfaces:

ether1
ether2
ether3
ether4
ether5
eoip-tunnel1
eoip-tunnel2
bridge1
bridge2

ether2, ether3, eoip-tunnel1 is members of bridge1
ether4, ether5, eoip-tunnel2 is members of bridge2

Currently
mac-address of bridge1 = mac-address of eoip-tunnel1
mac-address of bridge2 = mac-address of eoip-tunnel2

its normal, or all mac-addresses should be unique?

This is normal and desired.
A bridge gets the MAC address of the first interface assigned to it.
Imagine a bridge as a single interface with multiple ways in and out.
To make it reachable from each physical connection logically connected to it, it has to have a unique MAC address.

Bridges and tunnels can’t have mac-addresses cause they are virtual interfaces, not hardware. Bridge gets mac from ether/sfp interface, EoIP from bridge. It’s ok.
