Carlos,

are you trying to get your config from a remote tftp server at startup ? You probably have done this already, but you might want to check your config for a command like boot network tftp or boot system tftp, if those commands are in there remove them from your config.

If you follow the link below there is a document which explains some common TFTP errors, might be useful:

If you are loosing the config everytime you startup you might want to check the config register. Do a "sh version" and the bottom line should say Config register value. You need it to say 0x2102 so that the startup config is loaded at startup. To change this go into config mode and type "config-register 0x2102" and quit. Sh version again will say current value and what it will be at next boot up. Also, after you have done a "copy run start" (to save your config) try a "show start" to see if your config has ended up in the NVRAM. It should do!

If this was the case, someone may have 'broken into' the router via the console port at some point to bypass the login passwords.

Hope this helps.

Hello,

you might want to check if the command ´service config´ is configured on your router. By configuring ´no service config´ you can stop the broadcasts.

Georg,

Thanks for your input. Unfortunately I'm still getting the broadcasts. Should I try something else?

Sincerely,

Try "boot system flash "

If you don't know / can't remember the filename, do a "show flash" (dir might work too...can't remember)
