I used 2 ether ports (ether4, ether5) to setup a bond with 802.3ad mode between my mikrotik and cisco switch. I setup also a trunk to pass tagged all VLANs (10,20,30,40) and all works flawlessly.
The problem is when I want use ether3 port as a untagged of VLAN20, I tried to make a port bridge between bond and ether3 but not working. Someone can help me?
Is vlan-filtering=yes set on the bridge? Have you configured the following:
/interface bridge vlan
add vlan-ids=20 bridge=your-bridge-name tagged=your-bridge-name,your-bond-name untagged=ether3
