[ Tips: ] Reboot a remote Cisco router after an misconfiguration

Human error!!! ..... it is common, even in network administration. But if this happen on the remote router or switch that do not have person/human that can physically reboot the device then it is become....disaster!!!!

So what is the option? We can use a simple and tricky way to avoid this situation.
In Cisco router we can use command reload in minutes before you do the command input. So when everything become unaccessible, the router will reboot to startup-configuration .

In my case I use 5 minutes (may be different to other) :

Cisco# reload in 5

so when my router cannot be accessed, it will reboot in 5 minutes . After that I can access it again.

Then do the configurations. You must do it 5 minutes otherwise the router will be reboot.

But if the configuration is successfully done, do not forget to cancel it with:

Cisco# reload cancel

That's all !!
