LAGG + TRUNK with access to the same VLANs

[Kisiell]

Hello guys,

I'm wondering can anyone help me with some tricky configuration

I have 3 LAN interfaces and I would like to LAGG two of them and use as trunk, third single interface I would like to use as trunk as well but separate. LAGG and this single one should access the some VLANS....

   igb3 - WAN1

   ue0 - WAN2

   igb0 -
            > LAGG0 - trunk - VLAN 2, 3, 4, 5, 6
   igb1 -

   igb2 -  trunk  - VLAN 2, 3, 4

As you can see VLANs 2,3,4 should be accessible from all LAN interfaces.

igb0-1 are connected to two managed switches which are stacked.
igb2 is connected to third standalone managed switch.

I was trying to configure LAGG + igb2 as single bridge and add VLANs on top of BRIDGE interface but without success.
I was trying also to setup VLANS for LAGG and separate for igb2 and then bind them with bridge interfaces VLAN by VLAN but this also doesn't work.

THX in advance for any help on this...
