I am trying to solve the problem myself with this hotplug script which seems to be working for me as of today, though it certainly feels hackey maybe it could mature with experience. I’ve yet to drive around, but did test loss of signal with an attenuator, and based on your input about the Sierra handling tower switching (iirc I saw the same thing the documentation) that should mean that the only thing we need to be aware of from the MM/OpenWrt side of things is the state of the modem and whether the link is down, and then it’s just a matter of running ifdown to clear out the old routes and bearers then ifup.</div><div class=""><br class=""></div><div class="">I’m checking the modem’s state by (brace yourself) parsing mmcli output, and checking link connectivity by pinging over the modem interface.
