how to make sure bridge interface is up with netplan after reboot

[mabi]

Hello,

I am using Ubuntu 17.10 and therefore Netplan which I have configured a bridge for a specific network interface for my Xen virtual machines. Unfortunately when I reboot the server that bridge interface is in state DOWN so that I have to manually set it up using "ip link set xenbr1 up" command. Now does anyone know how to make sure netplan brings my bridge interface automatically up at reboot?

Here is the relevant part of my netplan netcfg.yaml file:

network:
  version: 2
  renderer: networkd
  ethernets:
    eno3:
      dhcp4: no
  bridges:
    xenbr1:
      interfaces: [eno3]
      dhcp4: no
      parameters:
        stp: no
        forward-delay: 0

Regards,
M.
