IP address in bridge or etherX

Hello,

I have a RB3011 router with last version: 6.41

I have configured the bridge this way:

/interface bridge port
add bridge=bridge interface=ether2
add bridge=bridge interface=ether6
add bridge=bridge interface=ether3
add bridge=bridge interface=ether4
add bridge=bridge interface=ether5
add bridge=bridge interface=ether7
add bridge=bridge interface=ether8
add bridge=bridge interface=ether9

I had assigned the LAN IP addres in the ether2 interface:

/ip address add address=192.168.2.1/24 interface=ether2 network=192.168.2.0

Now I change to bridge:

/ip address add address=192.168.2.1/24 interface=bridge network=192.168.2.0

Which is the difference? Which one is the recommended?

Both works well for me. I will really appreciate your help.

Kind regards.

Both works but it shouldn't and the proper way is to assign IP to the bridge.
The bridge is the interface which could have real ports attached to it but it is not neccessary.
If you assign any existing real interface to the bridge this interface should be treated since then only as an dumb electrical/wireless socket.
The bridge receives automatically the lowest MAC address from all interfaces assigned to it unless you specify it manually.
