Encoding Long Options in the Dynamic Host Configuration Protocol
RFC 3396, “Encoding Long Options in the Dynamic Host Configuration Protocol”, is a Proposed Standard document published in November 2002 by T. Lemon, S. Cheshire. It updates RFC 2131. The canonical text is published by the RFC Editor.
Abstract
This document specifies the processing rules for DHCPv4 options that appear multiple times in the same message. Multiple instances of the same option are generated when an option exceeds 255 octets in size (the maximum size of a single option) or when an option needs to be split apart in order to take advantage of DHCP option overloading. When multiple instances of the same option appear in the options, file and/or sname fields in a DHCP packet, the contents of these options are concatenated together to form a single option prior to processing.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
