Generalized UDP Source Port for DHCP Relay
Overview
RFC 8357, “Generalized UDP Source Port for DHCP Relay”, is a Proposed Standard document published in March 2018 by N. Shen, E. Chen. The canonical text is published by the RFC Editor.
Abstract
This document defines an extension to the DHCP protocols that allows a relay agent to use any available source port for upstream communications. The extension also allows inclusion of a DHCP option that can be used to statelessly route responses back to the appropriate source port on downstream communications.
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.
