Configuring a Router as a Server
It is too costly and inefficient to have a machine which only acts as server on every network segment.
However, when you do not have a server on every segment, your network operations can incur enormous
time delays across network segments. You can configure a router to serve as a RARP or TFTP server to
reduce costs and time delays in your network while allowing you to use your router for its regular
functions.
Typically, a router that is configured as a server provides other routers with operating system images
from its Flash memory. You can also configure the router to respond to other types of service requests,
such as Reverse Address Resolution Protocol (RARP) requests.
To configure the router as a server, perform any of the tasks in the following sections. The tasks are not
mutually exclusive.
• Configuring a Router as a TFTP Server
• Configuring a Router as a RARP Server
