Awaiting your valiable suggestion

Configure the router that has the desired image as TFTP server

I do not believe that it is a rubbish question. And the good news is that I believe that there is an alternative that will work for you. You can configure your 1700 router to function as a TFTP server and to serve the image file to the other 1700 routers. The configuration is quite simple:

tftp flash:

I have set it up on a 1721 and it works quite well. Note that this does not make the 1700 into a full TFTP server but it does allow it to serve its image file to other routers.

hai Rick,

I am really happy to see your reply .. first of all i never though that whis wud happen.

Tell me how do i can perform this

for eg ive connected two routers with Ethernet interface Router A has the IOS image which support BGP the other one (Router B) does not ... tell me how do i transfer the IOS image from Router A to Router B ....

in which router shud i use this command

tftp flash:

for Eg: if i use this in Router A .. how do i access this from Router B

Thanks once agin

i wud be happy if you cud expain step by step ..

ok - step by step:

- if routerA is the one that has the image that does support BGP then routerA is the one where you configure tftp flash:

- then from frouterB you issue the command:

copy tftp: flash:

when you enter this command it will prompt you for the IP address of the server (and you give it the address of routerA on the back to back connection. Then it prompts you for the source file name - and you give it the file name of the image on routerA, and it prompts you for the file name of the destination and you accept the default which is the same as the source name. After you answers the prompts then routerB will copy the image from routerA.

It sounds like the copy tftp flash did not work. Perhaps you could post the output of show flash from both routers?

One thing to check is if there is enough room for the new image in the flash of router A. Router A is running an older image and an image with fewer capabilities. The image from router B is newer, has more capabilities, and almost certainly is larger. Make sure that flash on router A has enough room to contain the new image. The output of show flash from both routers will help to answer this question.
