Pingu doesn't always add routes to main table when interface comes up
Pingu copies the default routes from each monitored interface into a different routing table, and then removes/adds them from/to the main routing table when the interface goes up/down.
However, several times now, we have discovered that the default routes on an Alpine-powered router have been “lost” — they aren’t there in the main table. In every case, pingu is still running, and considers one interface to be “up”. The default routes which it copied into tables 1 and 2 can be found there.
I intend to debug this myself, but am posting here to record the fact that a problem exists, and so that any others who are experiencing the same problem can post in the same thread.
