3-2Obtaining an IP Address DynamicallyA DHCP server can take the place of the BOOTP server in the following dynamic IP addressacquisition.A BOOTP client dynamically obtains an IP address from a BOOTP server in the following steps: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 correspondingIP address and other information according to the MAC address of the BOOTP client. The BOOTPserver then returns a BOOTP response to the BOOTP client.3) The BOOTP client obtains the IP address from the received response.Protocols and StandardsSome protocols and standards related to BOOTP include:z RFC 951: Bootstrap Protocol (BOOTP)z RFC 2132: DHCP Options and BOOTP Vendor Extensionsz RFC 1542: Clarifications and Extensions for the Bootstrap ProtocolConfiguring an Interface to Dynamically Obtain an IP AddressThrough BOOTPFollow these steps to configure an interface to dynamically obtain an IP address:To do… Use the command… RemarksEnter system view system-view —Enter interface view interface interface-typeinterface-number —Configure an interface todynamically obtain an IPaddress through BOOTPip address bootp-allocRequiredBy default, an interface doesnot use BOOTP to obtain an IPaddress.Displaying and Maintaining BOOTP Client ConfigurationTo do… Use the command… RemarksDisplay BOOTP clientinformationdisplay bootp client[ interface interface-typeinterface-number ]Available in any view
