Attempt to load image from rommon, but it keeps failing

Hi,

Imagine my C2610 router flash got corrupted. Every time I restart the router I get into rommon. Then I do 'dir' and I see only device 'flash' there. Trying to boot from flash doesn't go through.

I downloaded the image from cisco.com and I trying to load it following cisco document ID ID: 12714.

What I did:

I connected an ethernet cable to the e0/0 port on the affected router. At this point the router has no IP address configured, obviously.

Then I connected an ethernet cable from my laptop (where I have the C2600 image downloaded from cisco) on root drive c:.

Then on Hyperterminal, connected thru the console cable to the C2610 router I do on rommon as shown below.

Notice that my laptop NIC connected to the switch in which the C2610 e0/0 is also connected is IP=10.1.1.1/24.

What am I doing wrong ? Every single time the operation times out. See below.

Re: Attempt to load image from rommon, but it keeps failing

Hi,

This problem is due to same IP 10.1.1.1 is configured on TFTP server and router.

if you are directly connecting laptop configured with 10.1.1.1 to your router, you dont need gateway. assign IP 10.1.1.2 to router.

on your ROMMON prompt set parameters as shown below:

ommon 66 > IP_ADDRESS=10.1.1.2

rommon 67 > IP_SUBNET_MASK=255.255.255.0

rommon 69 > TFTP_SERVER=10.1.1.1

rommon 70 > TFTP_FILE=2600-advipservicesk9-mz.124-10.bin

rommon 71 > tftpdnld

while mentioning tftp file, you dont need to specify drive letter c: or d: because on your TFTP server you must have already set the path to C: where your IOS file is kept.
