    I want a cisco 805 router to boot its IOS image with tftp, but it always
    loads its old image from flash...
    I looked on the console suring boot time, it doesn't even try to boot via
    tftp, so it looks like the command boot system tftp c800-y6-mw.123-5.bin is ignored.
    I seem to do something wrong, maybe someone can help me.

    This is a part of my config:
    Current configuration:
    version 12.0
    no service pad
    service timestamps debug uptime
    service timestamps log uptime
    service password-encryption
    hostname Cisco805
    boot system tftp c800-y6-mw.123-5.bin
    ip subnet-zero
    ip name-server
    ip address-pool local
    process-max-time 200
    interface Ethernet0
    description connected_to_officenetwork
    ip address
    no ip directed-broadcast
    no keepalive

    Can you ping the tftp server once the router boots? The router will default
    to the flash image if it can't load an IOS that is listed in the boot system

    Hi Brian,

    Yes I can ping the router once it's booting.
    It seems it doesn't even try to tftp, I don't see messages saying it can't
    reach the tftp server, or if its trying to...

    It seems you are using supernetting ( Please check the
    subnet mask in your tftp server. Both are using the same. Also,
    disable any firewall software running in the server.

    Good luck,

    How does it find the tftp server?

    I have the same problem. But it occurs to me that as specified the router can never boot from tftp. When it first boots, it needs to contact the tftp server specified. But how can it do this? Until the ios and running config are loaded, there will be no functioning interfaces on the router, therefore there is no way for the router to contact the tftp server to load the ios in the first place. So booting from a network location seems to me to be a paradox!! Anyone shed any light on this???
