Hi DHC WG,
Jari, Mirja and I have just prepared a draft where it's shown how a new Use Case exists for a L2 Relay Agent for DHCP in IPv4.
We would like to propose the argument and collect comments on that with the objective to converge towards a solution.
The argument is important in the Radio Access Network in the scope of the current and future mobile networks and OpenRAN.

All opinions are welcome.
Claudio Porfiri

Title:    Layer 2 Relay Agents in Cellular Fronthaul Networks
Date:     2023-10-23
Group:    Individual Submission
Pages:    10
URL:      https://www.ietf.org/archive/id/draft-porfiri-dhc-dhcpv4-l2ra-fronthaul-00.txt
Status:   https://datatracker.ietf.org/doc/draft-porfiri-dhc-dhcpv4-l2ra-fronthaul/

Abstract:

   The fronthaul portion of a cellular network is the part of the
   network that connects centralized radio controllers and the
   distributed radio units at the edge of the cellular network.  A
   switched fronthaul network is one where the connectivity is provided
   through one or more stages of switches.

   When performing address assignment and configuration tasks in such
   networks, knowledge of how the different devices are connected is
   beneficial.  Networks that employ IPv6 can use DHCPv6 to support
   Relay Agents.  However, those networks that continue to be based on
   IPv4 have no easy way to support this, as the DHCPv4 support for
   relays is limited.

   This document explores how to provide Relay Agent functionality in
   IPv4-based switched fronthaul networks.
