Reset Ciscos to factory defaults

Hello All - I don't have very much cisco experience, so I hope someone
can answer this question. We recently switched over many of our PTP
T1's to VPN's. So now we have lots of extra cisco routers. I am
wanting to sell them on ebay, but I am not sure how to reset the
routers to factory defaults.

Is there an easy command that will reset the routers to defaults?

Any help would be appreicated. Thanks

 

erase nvram:

deletes startup-config and RSA keys. After the nvram filesystem is
initialized turn of the device.

 

Are there insturctions somewhere that takes me step by step through
those processes? I am not that familiar with cisco commands.

Thanks

 

I didn't know how to ddo this either, never having had to, so assuming
the advice above is correct (it looks OK):


attach a terminal (or a terminal emulator like hyperterminal) set to
9600,8,N,1 to the console port.

turn on the router.

Wait for it to boot.

type 'enable' (or just 'en') at the prompt.

type 'erase nvram'

wait until it completes.

turn off the router.

Turn it back on and it should come back with a default config.


BTW, what routers are they, and where are you?

 

Thanks for the help!

They we have 4 2620's and 2 2501's.
