I have a bridge created on my ubunut 16.04 box. The bridge does not get an IP from my DHCP server on the network on boot.
/etc/network/interfaces :
# interfaces(5) file used by ifup(8) and ifdown(8)
auto br0
iface br0 inet dhcp
bridge-ifaces eno1
bridge-ports eno1
up ifconfig eno1 up
iface eno1 inet manual
auto lo
iface lo inet loopback
When the machine is booted, it has no connection to the LAN, there is no internet connection. The IP's on my lan are 192.168.11.xx. The IP of the bridge on boot is 10.255.212.1.
On boot:
bas@Viky:~$ ifconfig

After boot this can be corrected by ifdown -a and ifup -a.

I don't understand why the bridge does not get an IP address from the DHCP server on boot.
Can anyone help met out with this please?
Where do I start on this networking challange?

(Because I did not get any response on this question, I figured it is to broad. Therefore made this sub question.)
