downloading config through a telnet session

[axfalk]

We have a situation where we are allowed an access to a CISCO router only through a telnet session. This router is being used for Disaster Recovery excercise and being constantly reused by different companies who are doing their excercises. So, when we're conducting our excercise, we would like to clear the original router's config and download ours from the tftp server. However, we are not sure if it's possible using a telnet session. Can anybody please shed the light on this?

Thanks.

I just tried it on an old 2509 we had on a shelf, running 11.1.

Using a telnet session, I erased the startup config, loaded my new config to nvram, and rebooted the router.

To erase the config - router# erase startup-config

To load the new config - router# copy config tftp

To reboot - router# reload

The reboot will automatically kill the existing running-config and copy the startup from nvram to ram (running).

Hope this helps.
