I am in the process of upgrading the rommon (bootstrap) of a Cisco 2621 router, the only method i've reached is to go to the rommon mode and do the following:
> rommon 4 > IP_ADDRESS=<ip_address_for_the_local_router>
> rommon 5 > IP_SUBNET_MASK=<subnet_mask>
> rommon 6 > DEFAULT_GATEWAY=<gateway>
> rommon 7 > TFTP_SERVER=<tftp_server_ip>
> rommon 8 > TFTP_FILE= c2600-i-mz.123-22.bin
> rommon 9 > tftpdnld -u
The problem is that when i did everything i was astonished that my router doesn't support the "-u" key, while other routers does.
Has any one faced this problem, or know a solution? I need to upgrade the rommon in order to support new features (like "no service password-recovery").
Thanks in advance,
