Production internetworks usually span wide areas and contain multiple routers. For any
network, it is always prudent to retain a backup copy of the Cisco IOS Software image in
case the system image in the router becomes corrupted or accidentally erased.
Widely distributed routers also need a source or backup location for Cisco IOS Software
images. Using a network TFTP server allows image and con?¬?guration uploads and
downloads over the network. The network TFTP server can be another router, a workstation,
or a host system. Figure 6-11 illustrates copying ?¬?les to and from a network server.
