        <pre>Hi,

I got the simplest possible Bridge setup. 

foo.network
[Match]
Name=enp*

[Network]
Bridge=br0

bar.network
[Match]
Name=br0

[Network]
DHCP=v4

and of course the bridge.netdev.


Everything works fine and i can connect containers etc. to the bridge until i
suspend my computer. 
After the wakeup, the network is not coming back up. I only get "br0 lost
carrier" in the journal. 
If I restart systemd-networkd.service everything works fine again.

Do you need more infos? Can you reproduce this behaviour?


Greetings</pre>
