BOOTP Client
Configuration
This section contains configuration information for BOOTP Client.
Overview of BOOTP
Client
A BOOTP client can request the server to allocate an IP address to it using BOOTP
(bootstrap protocol). These two major processes are included on the BOOTP client:
■ Sending BOOTP Request message to the server
■ Processing BOOTP Response message returned from the server
In obtaining an IP address using BOOTP, the BOOTP client sends the server the BOOTP
Request message. Upon receiving the request message, the server returns the BOOTP
Response message. The BOOTP client can then obtain the allocated IP address from
the received response message.
The BOOTP message is based on UDP, so a retransmission mechanism in the event of
timeout is used to guarantee its reliable transmission. The BOOTP client also starts a
retransmission timer when it sends the request message to the server. If the timer
expires before the return of the response message from the server, the request
message will be retransmitted. The retransmission occurs every five seconds and the
maximum number of retransmissions is three, that is, the message shall not be
retransmitted after the third time.
