A DHCP server can take the place of the BOOTP server in the following dynamic IP
address acquisition.
A BOOTP client dynamically obtains an IP address from a BOOTP server in the
following way:
1 The BOOTP client broadcasts a BOOTP request, which contains its own MAC
address.
2 The BOOTP server receives the request and searches the configuration file for the
corresponding IP address according to the MAC address of the BOOTP client. The
BOOTP server then returns a BOOTP response to the BOOTP client.
3 The BOOTP client obtains the IP address from the received the response.
Some protocols and standards related to BOOTP include:
1 RFC 951: Bootstrap Protocol (BOOTP)
2 RFC 2132: DHCP Options and BOOTP Vendor Extensions
3 RFC 1542: Clarifications and Extensions for the Bootstrap Protocol
Follow these steps to configure an interface to dynamically obtain an IP address:

Network requirements
The interface Ethernet1/1 of Router B acting as a client is connected to the LAN to
obtain an IP address from the DHCP server by using BOOTP.
Network diagram
See Figure 170.
Configuration procedure
The following describes only the configuration on Router B serving as a client.
Use the command...
system-view
interface interface-type
interface-number
ip address bootp-alloc
Use the command...
display bootp client
[ interface interface-type
interface-number ]
