Add routing entry at system startup
 

I hv added the below routing entry to my system , but it will be erased after system reboot , how to set it as a permanent routing so that it still vaild even system reboot ? thx

I don't see the "below" entry, but there are a number of startup scripts, like the "rc" scripts that your system probably runs. You should look up documentation on startup scripts and rc files for your distribution and then its probably just a matter of adding that line "route add" whatever to a startup script file.
