YANG Data Model for DHCPv6 Configuration
draft-ietf-dhc-dhcpv6-yang-09
This document describes a YANG data model [RFC6020] for the configuration and management of DHCPv6 servers, relays, and clients.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].
This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering Task Force (IETF). Note that other groups may also distribute working documents as Internet-Drafts. The list of current Internet-Drafts is at https://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress."

DHCPv6 [RFC3315] is widely used for supplying configuration and other relevant parameters to clients in IPv6 networks. This document defines a DHCPv6 YANG data model, containing sub-modules for the configuration and management of DHCPv6 servers, relays and clients. A single YANG model covering all of these elements provides an operator with a common interface for the management of the entire DHCPv6 deployment in their network.
Since the publication of the original DHCPv6 specification, there have been a large number of additional documents that update the protocol's operation, add new functions and define new options. The YANG model described in this document incorporates all relevant changes. A full list of the documents which have been considered in the development of this model is included in Appendix A.
IF - Comment - Does anyone have this list?
It is worth noting that as DHCPv6 is itself a device configuration protocol, it is not the intention of this document to replace the configuration of DHCPv6 options and parameters using the DHCPv6 protocol with the configuration of DHCPv6 options using NETCONF/YANG. The DHCPv6 client model is intended for the configuration of the DHCPv6 client function and also for obtaining read-only state data from the client which has been learned via the normal DHCPv6 message flow. This gives an operator a better method for managing DHCPv6 clients and simplifies troubleshooting.
The reader should be familiar with the terms defined in DHCPv6 [RFC3315] and other relevant documents.
The DHCPv6 tree diagrams provide a concise representation of a YANG module to help the reader understand the module structure.
A simplified graphical representation of the data model is provided in this document. For a description of the symbols in these diagrams, please refer to [I-D.ietf-netmod-yang-tree-diagrams].
