Add static route via script

  • Reboot devices to clean all static routes and access via SSH/Telnet to AirOS device
  • Create a script /etc/persistent/rc.poststart and write here commands to add static route
  • Make sure that /etc/persistent/rc.poststart are executable
  • Check if your script work fine running the command line: ./etc/persistent/rc.poststart
    note: the command now start with a "dot" = run the script!
  • Run the command: cfgmtd -w -p /etc/ to make persistent
  • Reboot and verify that all it's working...
