                A YANG Data Model for Keyed IPv6 Tunnels
               draft-ietf-l2tpext-keyed-v6-tunnel-yang-02

Abstract

   This document defines a YANG data model for the configuration and
   management of Keyed IPv6 tunnels.  The data model includes both
   configuration and state data.  Due to the stateless nature of keyed
   IPv6 tunnels, a model for NETCONF notifications is not necessary.

Requirements Language

   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.

1.  Introduction

   Keyed IPv6 Tunnels [I-D.ietf-l2tpext-keyed-ipv6-tunnel] defines a
   mechanism for transporting L2 Ethernet frames over IPv6 using L2TPv3
   tunnel encapsulation with a mandatory 64-bit cookie.  It is a static
   layer 2 tunnelling mechanism that leverages IPv6's vast number of IP
   addresses to uniquely identify each tunnel, instead of using the
   L2TPv3 Session ID as the differentiator (as defined in [RFC3931]).
   The layer 2 circuit is mapped to an IPv6 address on the network side
   so typically, there is one session per-tunnel.

   Since the L2TPv3 control plane is not used by Keyed IPv6 tunnels, the
   parameters for building a Keyed IPv6 tunnel need to be pre-configured
   on the two tunnel endpoint devices.  NETCONF [RFC6241]/YANG [RFC6020]
