systemd-networkd and bonding




I'm running Debian/Stretch (AMD64).

I'm trying to create a bond between two network devices (currently testing on my laptop but also have a couple of servers I'd like to use it on) following the Debian Wiki at https://wiki.debian.org/Bonding.

I got the ifenslave method working as per the first two examples. Then I noticed the systemd-networkd method which looks to be the way of the future. I put the laptop's networking back to it's original settings and removed ifenslave then proceeded with the example, changing the bond device's IP to one that works on my network.

The network seems to come up and the bond device has the correct IP but my network doesn't work. Since Mode=802.3ad could have problems, I switched it to active-backup, which worked with ifenslave. Rebooting was slow and when I logged in, I found the network still wasn't working, although ifconfig showed exactly what I thought I should see (the bond device with an IP address and the two slave devices working but without an IP).

There's not a lot of online documentation that I've found that doesn't use ifenslave. Has anyone got this to work using systemd-networkd?

Also, for my laptop, using dhcp to set the IP makes more sense. The wiki article sets a static IP:

[Match]
Name=test-lag
[Network]
Address=192.168.1.13/24
Gateway=192.168.1.1

is how I set it on my laptop. What would that be for a dhcp IP address?

Thanks.
