How to mesh over ethernet VLAN?

Hello everybody,

What's the correct setup to mesh also over an existing ethernet VLAN link?

My core network with all routers & servers is running on VLAN 3 (eth0.3 in the routers). How do I have to setup batman-adv to a) mesh also over this existing link and b) propagate this VLAN also over wireless links. Bridging eth0.3 with bat0.3 and adding eth0.3 also as a hardif doesn't work, as it will remove eth0.3 from the bridge.

If I add eth0 instead as hardif the routers are only seeing each other over wireless link. Or do I have to use a separate VLAN for ethernet meshing which isn't bridged to a bat0.X interface?

Thanks a lot!
