VLAN bridge traffic

RouterOS General
1

Hello,

I have two bridges on MT:
Bridge 1:
—ether 1(Tagged) ----- vlan 10 (MT) -------- (Tagged)ether 4 -----

Bridge 2:
----ether 2(untagged) -------vlan_wl(MT) --------(untagged)ether 3 -----------

Is this normal that all incoming traffic from ether 1 is forwarded to ether 4 ? Even if device(MT) connected to port ether 4 have port disabled ?

Thanks.

Try posting your actual bridge configs - the diagram isn’t totally clear.

Bridge_Manage = Bridge1 in my picture
Bridge_vlan_10 = Bridge2 in my picture

/interface bridge port
add bridge=Bridge_vlan_10 disabled=no edge=auto external-fdb=auto horizon=none interface=vlan_10 path-cost=10
point-to-point=auto priority=0x80
add bridge=Bridge_Manage disabled=no edge=auto external-fdb=auto horizon=none interface=ether1 path-cost=
10 point-to-point=auto priority=0x80
add bridge=Bridge_vlan_10 disabled=no edge=auto external-fdb=auto horizon=none interface=ether2
path-cost=10 point-to-point=auto priority=0x80
add bridge=Bridge_vlan_10 disabled=no edge=auto external-fdb=auto horizon=none interface=ether3 path-cost=
10 point-to-point=auto priority=0x80
add bridge=Bridge_vlan_10 disabled=no edge=auto external-fdb=auto horizon=none interface=ether5 path-cost=10
point-to-point=auto priority=0x80
add bridge=Bridge_Manage disabled=no edge=auto external-fdb=auto horizon=none interface=ether4 path-cost=10

/interface bridge settings
set use-ip-firewall=yes use-ip-firewall-for-pppoe=no use-ip-firewall-for-vlan=yes

This config would bridge Ether1 and Ether4. If the device attached to a bridge port has the link disabled then that bridge port will be flagged as down.

Perhaps you can describe your expected behaviour and observed behaviour in more detail. The question is unclear.

I have another MT(2) connected to ether4, but this MT(2) have port disabled. I see a big traffic on first MT(described above) in TX packet on port ether 4, why ? I expected that there won’t be any traffic.

Or in another way, if i have bridge with two tagged ethernet port, all incoming traffic from one port will be forwarded to antoher port or only traffic which should go to second ethernet port will be forwarded ?
