Harold,
After you have your out file and transfer to target, OpenWrt needs the package
'libstdcpp6' installed to run it. I use the OpenWrt Firmware Selector to make a
firmware image including this and all other packages I desire (e.g. Wireguard - I'm on
the East coast; but I recall someone said they wanted a tunnel onthe West Coast).
I use the /etc/config folder to save ampr-ripd and encap.txt (i.e. they can be added to
the backup config file). These file directory details are in the wiki example.
