TCP/IP Protocol Suite 1 Chapter 16 Upon completion you will be able to: Host Configuration: BOOTP and DHCP Know the types of information required by a system on boot-up Know how BOOTP operates Know how DHCP operates Understand the differences between BOOTP and DHCP Understand the DHCP transition state diagram Objectives

TCP/IP Protocol Suite BOOTP The Bootstrap Protocol (BOOTP) is a client/server protocol that configures a diskless computer or a computer that is booted for the first time. BOOTP provides the IP address, net mask, the address of a default router, and the address of a name server. The topics discussed in this section include: Operation Packet Format

TCP/IP Protocol Suite 3 Figure 16.1 Client and server on the same network

TCP/IP Protocol Suite 4 Figure 16.2 Client and server on two different networks

TCP/IP Protocol Suite 5 Figure 16.3 Use of UDP ports

TCP/IP Protocol Suite 6 Figure 16.4 BOOTP packet format

TCP/IP Protocol Suite 7 Figure 16.5 Option format

TCP/IP Protocol Suite 8 Table 16.1 Options for BOOTP

TCP/IP Protocol Suite DHCP The Dynamic Host Configuration Protocol (DHCP) provides static and dynamic address allocation that can be manual or automatic. The topics discussed in this section include: Static Address Allocation Dynamic Address Allocation Manual and Automatic Configuration Packet Format Transition States Exchanging Messages

TCP/IP Protocol Suite 10 DHCP provides static and dynamic address allocation that can be manual or automatic. Note:
