flash tftp. This command tells the router to copy the contents of flash
memory (this is where the IOS is stored by default) to a TFTP host.
6. Enter the IP address of the TFTP host and the source IOS filename.
The file is now copied and stored in the TFTP host’s default directory.
Lab 7.2: Upgrading or Restoring Your Router IOS
1. Log in to your router and go into privileged mode by typing en or
enable.
2. Make sure you can connect to the TFTP host by pinging the IP address
of the host from the router console.
3. Once you know you have good Ethernet connectivity to the TFTP
host, issue the copy tftp flash command.
4. Confirm that the router is not functioning during the restore or
upgrade by following the prompts provided on the router console.
5. Enter the IP address of the TFTP host.
6. Enter the IOS filename you want to restore or upgrade.
7. Confirm that you understand that the contents of flash memory will
be erased.
8. Watch in amazement as your IOS is deleted out of flash memory, and
your new IOS is copied to flash memory.
If the file that was in flash memory is deleted, but the new version wasn’t
copied to flash memory, the router will boot from ROM monitor mode.
You’ll need to figure out why the copy operation did not take place.

1. Log in to your router and go into privileged mode by typing en or
