When iocage jail starts, a different lagg is added to the bridge, creating network loop

    Details

      Description

      I have 2x 2-port laggs running LACP

      1. lagg0 = LAN - native VLAN1
      2. lagg1 = DMZ/Infrastructure - no native VLAN but 3 trunked VLANs

      I have 3 VLANs mapped to lagg1 only:

      1. DMZ
      2. Infrastructure
      3. Media

      I have 3 corresponding bridges that map to their corresponding VLAN

      1. DMZ
      2. Infrastructure
      3. Media

      I have total 6x Jails, 1x to DMZ bridge, 3x to Infrastructure bridge, and 2x to media bridge

      When I add my VMs to bridge2 (infrastructure seems most impacted by this, but same happens on other bridges too), I start seeing packet loss.

      Before starting the bridge the only member is the (correct) VLAN

      However after I start one of the VMs that is set to use bridge2, I note that not only do I see the VLAN as a member, but also the lagg0 device.

      It's not clear to me if this is a problem in the configuration of the VMs, the bridge, the VLAN, or maybe the lagg.  I have remvoed and re-added the bridges and VLANs multiple times - to realise the same impact
