Transmitting on bridge port when no MAC addresses seen

Hi there,

I am using an RB450G running RouterOS 4.10 to try and have a dual outbound link for a customer using a bridge.
I am having some issues however with the bridge transmitting the traffic to both physical ports assigned to it even when the second CPE unit has its LAN disabled.
The type of CPE equipment we are using has the ability to disable its LAN port via adding a firewall rule to deny all traffic.
It doesn’t bring the port physically down but stops any MAC addresses being seen by the Routerboard.
When the second unit has its port disabled, the routerboard cannot see any MAC addresses on the port yet it is still transmitting outbound traffic at the same rate it is transmitting the same traffic out the first port.
I have pasted relevant configs below and have drawn a quick diagram to aid understanding.
Sorry if it looks a bit pre-school.
Any help with this would be much appreciated.

try setting a unique admin-mac on each bridge separately? Just a shot in the dark.

Hi changeip,

Thank you for the suggestion.
I have tested this and unfortunately it doesn’t solve the problem.
Does anyone else have any other ideas?
Any input would be appreciated.

Thanks

Does anyone have any ideas?
Still can’t figure out a solution to this.
