<div><p>Bootstrap Protocol (BOOTP) provides a dynamic method for associating
|
|||
|
|
workstations with servers and assigning workstation IP addresses and initial
|
|||
|
|
program load (IPL) sources. </p>
|
|||
|
|
<p>BOOTP is a TCP/IP protocol used to allow a media-less workstation (client)
|
|||
|
|
to request a file containing initial code from a server on the network. The
|
|||
|
|
BOOTP server listens on the well known BOOTP server port 67. When a client
|
|||
|
|
request is received, the server looks up the IP address defined for the client
|
|||
|
|
and returns a reply to the client with the client’s IP address and the name
|
|||
|
|
of the load file. The client then initiates a TFTP request to the server for
|
|||
|
|
the load file. The mapping between the client hardware address and IP address
|
|||
|
|
is kept in the BOOTP table on the system.</p>
