Do they have the same feature set? (adv. ip services, enterprise, etc..)

does the router support 'show ip nhrp'
Commented:
as per ddiazp

Just do a sh ver on each router to verify.

Thanks for your replies.
The newer router has an older compile date and does not support show ip nhrp, how do I fix this:?

You will need to download the image from cisco.com if you need it to support DMVPN/nhrp.  If you post the output of sh ver from each device - we can advise you.  In order to get the correct image, you need a CCO account from Cisco or have smartnet support though.

Or if you haven't contract try to tftp the new image  from the new router to the old!

@ikalmar: the other way around. Older router's image to the newer one according to gregbinns :)


Set up a tftp server on your machine, make sure you can ping the router you want to get the IOS from, and type:

#copy flash:imagename.bin tftp:

follow the 3 prompts for tftp ip address, file source name and file destination.

Once done, do the same with the other router (to have a backup copy of its current IOS)

then, do:

#copy tftp: flash:imagename.bin

and follow the 3 prompts for tftp ip address, file source name and destination


You should now end up with the new and old IOS on the TFTP server, and both routers with the IOS that supprots nhrp

the better way to copy from each other, becouse you able to do it without TFTP server!

type on the new router on the configuration:

eaxample
#tftp-server flash:c181x-advipservicesk9-mz.124-15.T1.bin
set up the routers same ip network, if each other able to ping ho the old console

copy tftp: flash:imagename.bin
 
Good luck

Commented:
Problem with that is that he might not have enough flash to store 2 IOS, and it's a good idea to backup his current IOS in case he ever needs to go back.

However, good suggestion

Thanks for all your help "but" is it possible to use ftp rather that tftp or should I set up tftp for general usefulness.

AND the routers are on different networks so I need to save the image and move it to the other network.

Commented:
routers use tftp, gotta do it that way :).

That's the one I use. Easy to set up and pretty straight forward. You dont have to worry about usernames/passwords.

Download that, use the copy commands I mentioned earlier to put both images in the tftp server, then copy the good one into the router with the bad one.
