1. Introduction

   YANG [RFC6020] is a data definition language that was introduced to
   define the contents of a conceptual data store that allows networked
   devices to be managed using NETCONF [RFC6241].

   This document presents YANG [RFC6020] data model for the
   operation of TRILL base protocol [RFC6325].

2. 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].

3. Design of Data model

   There is only one module for the TRILL base protocol [RFC6325]. The
   module can be augmented for other TRILL extended features with their
   specific definitions, such as TRILL active-active connection, TRILL
   Fine Grained Label, and etc.
   The TRILL Yang module includes one container named trillSites which
   contains a list of TRILL instances as single RBridge MAY support
   multiple TRILL instance. The configuration data is divided into four
   categories which are per RBridge, per nickname per RBridge, per port
   per RBridge and per VLAN per RBridge. The non-configuration data
   includes the information of LSDB, unicast and multicast routing
   table, RPF check, nickname, peer and some statistics.

   The figure below describes the overall structure of the TRILL Yang
   model. The following notations are used within the data tree.
       rw  for configuration data
       ro  for non-configuration data

5. Security Considerations

   The YANG module defined in this memo is designed to be accessed via
   the NETCONF protocol [RFC6241] [RFC6241]. The lowest NETCONF layer
   is the secure transport layer and the mandatory-to-implement secure

   transport is SSH [RFC6242] [RFC6242]. The NETCONF access control
   model [RFC6536] [RFC6536] provides the means to restrict access for
   particular NETCONF users to a pre-configured subset of all available
   NETCONF protocol operations and content.
