BOOTP Vendor Information Extensions

Status of this Memo

used in the Bootstrap Protocol (BOOTP). Distribution of this memo is

Introduction

This RFC is a slight revision and extension of RFC-1048 by Philip

Prindeville, who should be credited with the original work in this

memo. This memo will be updated as additional tags are are defined.

This edition introduces Tag 18 for Extension Path.

As workstations and personal computers proliferate on the Internet,

the administrative complexity of maintaining a network is increased

by an order of magnitude. The assignment of local network resources

to each client represents one such difficulty. In most environments,

delegating such responsibility to the user is not plausible and,

indeed, the solution is to define the resources in uniform terms, and

to automate their assignment.

The basic Bootstrap Protocol [RFC-951] dealt with the issue of

assigning an internet address to a client, as well as a few other

resources. The protocol included provisions for vendor-defined

resource information.

This memo defines a (potentially) vendor-independent interpretation

of this resource information.

Overview of BOOTP

While the Reverse Address Resolution (RARP) Protocol [RFC-903] may be

used to assign an IP address to a local network hardware address, it

provides only part of the functionality needed. Though this protocol

can be used in conjunction with other supplemental protocols (the

Resource Location Protocol [RFC-887], the Domain Name System [RFC-

1034]), a more integrated solution may be desirable.

Bootstrap Protocol (BOOTP) is a UDP/IP-based protocol that allows a

booting host to configure itself dynamically, and more significantly,

without user supervision. It provides a means to assign a host its

IP address, a file from which to download a boot program from some

server, that server's address, and (if present) the address of an

Internet gateway.

One obvious advantage of this procedure is the centralized management

of network addresses, which eliminates the need for per-host unique

configuration files. In an environment with several hundred hosts,

maintaining local configuration information and operating system

versions specific to each host might otherwise become chaotic. By
