Lab Challenge: Reload Router By Telnet

Here's a little challenge, I thought of this during my train trip when I was going home this evening. This should be pretty easy. Consider the diagram below and the scenario.

Configure a default route from R1 pointing to R2's ip address. The challenge is to reboot R1
from a telnet command from R3 without typing the command "reload". R3 should not telnet
directly to but instead it should telnet port 3000 to get to
port 3005. R1 should automatically ask to proceed to reboot and not ask for username/password
once the telnet from R3 is executed.

I believe this should be pretty easy for everyone. Let me know your thoughts on how to solve this challenge. I will post a blog entry regarding this for the next post. For now I need to get back to the belly of the IOS beast. Cheers!

What about the Warm Reload?

Warm reload is still reload... you type in warm-reboot command. The condition is you don't type any reboot or reload commands, the router automatically asks for a reload Yes or No Question when you telnet.

I think it is about time that you provide us with the answer. Don't you ?

Request granted. Been busy all these past few months.

I know you posted this teaser some time back but I have just found your site. I must say I am disappointed by the solution since in the end you still used the reload command - OK you did not type it at the time of the actual reboot. I thought you were going to illustrate a new way to reboot a Cisco device by maybe executing a CPU reboot or something like that. Never mind you got me thinking.

Nice site by the way and thank you for the labs and explanations.

Good luck in your pursuit of the CCIE qualification.
