tftp config copy question

[BGT]

I just got back from my class and we ran into a snag or theory problem maybe
one of yall smart cisco guys can help out on! :)

We were working on wiping out the running and starting config in the router
and then reloading it from a tftp server. Well, we found out that after you
wiped out running and starting configuration, your interfaces are wiped out
too so you cant access the tftp server.

Sooo, my question is: if your router is messed up and you want to reboot
from tftp server, why is the IOS setup to look at NVRAM first and the for a
tftp server if perchance, that network/interface is down and cant even get
to it??

i hope this wasnt a dumb question but it stumped me and couple other
students too. Thanks!

The ICND book, page 128, answers your question. If the device it is not
configured, it will go into the setup dialog mode right after the POST. For
the startup config to be loaded into the running config you have to tell the
router where to get it. In other words, you need to minimally configure it
to know where to find its running config.

Here's what I practice doing in my sem 2 academy class,If you type
in "start erase" in global config mode then type "reload",the router
will restart and the running config will be gone(its stored in volital
ram) when the router comes back on and it cant find a config file it
will prompt you to enter setup mode and enter a simple running
configuration.With that it will tell you that if you need to add
further configurations to do it through command line entries.Or with
the simple config up you can get your file from tftp then "copy tftp
start"check it out make sure its what you want then "copy start run"
Im sure im doing extra steps or something,Im just in semester 2 ccna
academy but this worked for me.
good luck with the learning
