<p>I wasn't clear what I meant about processing of the .network
file. With Ethernet or Wi-Fi (using iwd), when the link comes up,
systemd-networkd does the Right Thing and starts network services
on the interface, running a DHCP client or setting up static
address(es), routes, etc., as specified in the .network file. When
ModemManager establishes the connection with the 3G carrier,
systemd-networkd seems to be unaware of the event, and I have to
poke it with "systemd restart systemd-networkd" or "networkctl
reload" before it tries to use the information in the .network
file for the interface. It seems to me like that ought to happen
automatically. I suspect that ModemManager needs to be changed to
inform systemd-networkd.</p>
<p>So far, it's not looking like there's an effort to integrate
ModemManager (or something similar) with systemd-networkd, which
is kind of a shame. If I come up with anything useful toward
making that happen, I'll offer a pull request, but at the moment
I'm looking at cobbling something together with Python.<br>

<pre class="moz-quote-pre" wrap="">I took a closer look at what's going on with systemd-networkd, and I
found whether I use ModemManager or mbim-cli to connect to the mobile
network, the .network file will be processed, but _only after I restart
systemd-networkd_.

<pre class="moz-quote-pre" wrap="">I'm not 100% sure this applies to all the applications in the systemd ecosystem (like systemd-networkd), but systemd is reloading .unit, .service, .mount and all the other files there are only after a `systemctl daemon-reload`. That's the intended behaviour. Just wanted to mention this. Can't comment on anything else, though, as I have no clue either. But I'm interested in this topic and am silently monitoring this thread.</pre>
