Cisco Router Stuck

Hi all,

I have bought a CCNA lab off ebay and now having received it, it appears one of the routers will not boot?

it gets stuck at:

I can get to the rommon prompt by using the break key, so are there any commands I can issue at that stage which would fix this? or do I need to send it back? :/

cheers

thanks for that, I have tried the confreg 0x214 and it got stuck at the same place.

I have only literally just started the CCNA so most of that is double dutch to me... :L

which other ones should I try?

It may be the image is messed up. Do you have 2 of the same router? You could pull the image off the working one and tftp it onto the borked one

Have a look at this, only skimmed it but should have the basic details

As above, it sounds like you may need to recover the IOS, using a TFTP server is the easiest way to achieve this.

Do you know the Flash / RAM available on the router? This will help immensely in getting the correct IOS.

I do have another identical router yes. So would I just pull the image of that and install it onto the currently not working one?

again absolutely no idea how to do that... step by step guide will be needed :L

Boot up the working router and configure an interface on it with a valid IP address etc. Then connect your computer into it, set an IP address on the same subnet and install a TFTP server such as the 3Com one or Solarwinds.

Once done just run the TFTP server and on the router copy the IOS to the TFTP server from the CLI

copy flash:/<whatever-2600-image-you-have.bin> tftp

Then follow the prompts, should be pretty simple to follow even if you haven't done it before providing you have at least basic networking knowledge which I assume you do as you bought a kit!

HERE

Once done boot the other borked router into ROMON and follow the first guide, setting it's IP, subnet and the tftp server etc. then just pull the IOS over

This is one of those skills you will need at some point or other if you choose a career using these things, best thing is to have a play but those 2 links should sort you out
