In IOS boot sequence if the flash is erased, and there is
no access to TFTP server, and we can't load the partial IOS
from ROM. Is there any possiblity that we can still boot
the router/switch from external PC in which the IOS is
installed?

Answer Posted / s.m.feroz ahmed

Hi,

1) IOS is an operating system installed on Router.
2) Flash is a startup and running configuration on IOS
3) TFTP is a freeware one can install anytime.

If Flash is deleted one can restart router by restarting
while restarting press Pause|Break it will take to router
IOS mode copy the startup configuration to TFTP server and
try to do changes and restart router and you are into
router config .
