ROS stops sending ARP reply when 2nd VLAN is added to a bridge!

RouterOS General
1

Hi all,

I have an issue with ROS. Maybe it is only a wrong configuration or some limitation that I am not aware of.

The fact is that the following lines have has a result the ROS replying to the ARP request on VLAN4 with the proper TAG-ID.

/interface vlan
add interface=ether1 name=vlan4 vlan-id=4
add interface=ether1 name=vlan5 vlan-id=5
/interface bridge
add name=br-switching
/interface bridge port
add bridge=br-switching interface=vlan4
/ip address
add address=192.168.2.2/24 interface=br-switching network=192.168.2.0

If, afterwards, I add the following lines the ROS stops replying to the ARP requests!!!

/interface bridge port
add bridge=br-switching interface=vlan5

Can someone explain me why this?

Thanks in advance.
