So I recently changed my server from a Debian based distribution that used the old ifupdown style configs over to systemd-networkd.

What I want is, my two primary interfaces, bonded, and then a bridge attached to that bonded interface.

There will be an interface on the bridge, for the server, in the below example this is bridge0.2. The intention is that the host can communicate with guests operating on bridge0. VMs, and containers might be attached to bridge0. They may be on whatever VLAN they choose.

With that I had this configuration:

/etc/network/interfaces

auto lo
iface lo inet loopback

iface eth0 inet manual
iface eth1 inet manual

auto bond0
iface bond0 inet manual
  bond-slaves eth0 eth1
  bond-mode 802.3ad
  bond-xmit-hash-policy layer2+3

auto bridge0
iface bridge0 inet manual
  bridge-ports bond0
  bridge-stp off
  bridge-fd 0
  bridge-vlan-aware yes
  bridge-vids 2-4094

auto bridge0.2
iface bridge0.2 inet static
  address 192.168.2.253/24
  gateway 192.168.2.1

I've tried to repeat the same thing with systemd-networkd. I can get VLAN 2 up on a bonded interface, but I can't seem to get the VLAN on the bridge up.

If I do DHCP=true on the bridge0 interface, I can an address via VLAN=1. This makes me think there's some issue with the VLAN exiting the bridge.

I've tried for far too long to get this to work, and I really don't know what other combination to try. Here is what I have:

10-all-nic-to-bond0.network

I think I got this working, it was VLANFiltering=true that was causing the issues, changing this to false allowed me to exit the bridge on VLAN2.
