Please set the baud rate to 115200, otherwise the transfer will take ages to complete.

Excuse me, why is that one has have to use xmodem when LAN interface are avaialable ?

At rommon prompt, type "tftpdnld". It will list the variables that need to be set. Set themform rommon promtp, connect tftp server to router lowest lan interface and repeat tftpdnld.

Hope this helps, please rate post if it does!

bevilacqua has nailed it. it will take ages with xmodem (i have used it when i was not aware abt the rommon procedure).. :)

attached is the doc for this process ( for 2600 router, will be same for 3700 also)

chk the "Copying an Image from a TFTP Server Using the tftpdnld Command " section.

As you know I have router 3725 and the reason why i was upgrading the image was when I try to configure BGP router ASN it gives Protocol not in this Image and even after image upgrade ( now c3725-ipbase-mz.123-9e) it shows the same please help

You may need "sp" or "advanced ip services" image for BGP, not "ip base".

Hope this helps, please rate post if it does!
