Comment 19 for bug 1766542

I had to tweak the time outs a bit, as I quickly get some errors from the networking stack (like 7s or so), but I could successfully verify the fix now, using a standard ubuntu:bionic lxd container, and modifying the routes, and setting a lower timeout:

+ ip r del default
+ ip r add default via 10.33.102.254 dev eth0
+ ip -6 r del default
+ ip -6 r add default via fe80::689a:53ff:fe6f:8f85 dev eth0
