Ubuntu 16.04, does something remember network state at reboot?

I have two systems using keepalived with scripts which run at all state transitions (backup, fault, master).  At bootup these scripts document the network configuration (ip addr, ip ro) when they are launched (master state is assumed thus running the master script until determined differently at which time the backup script runs because it is the backup system - I'm testing with it).

What I'm seeing is a route which is only set by the backup keepalived script, I've checked /etc/rc.local (has only 'exit 0"), /etc/network/interfaces and its "source" file and OpenVPN (which, at the point of documentation, isn't running) - none refer to this specific route.  I've looked around under /lib/systemd but haven't found anything either.

This leads me to my question, "Does something remember network state at reboot?", I'm using the reboot command to reboot.  Thanks for any and all help, I'm totally baffled.
