Something I’ve noticed with recent builds, is I’ll have a ZT interface assigned to a bridge in linux, and when the host is rebooted, ZT says it comes up fine and is connected, as well as the bridge interface, but the routes I expect to see from ZT are not appearing in the routing table (Debian 11).
A systemctl restart zerotier seems to then propagate the routes into the table, and then any subsequent changes also appear in the table, but this seems to be a bit of a bug unless I’m missing something.
I have considered putting a delay on starting the ZT service to see if that fixes the issue, or just setting remote hosts to restart the service every 6 hours or so, but I didn’t see this behavior on the 1.8.x branch.
