Internet-Draft          TRILL YANG Data Model             January 2015


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 defines a YANG [RFC6020] data model for the operation
   of TRILL base protocol.

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. 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 of trillSites which
   contains a list of instances as many implementations are currently
   supporting multiple ISIS instances within a single RBridge. The
   configuration data is divided into four categories which include per
   RBridge, per nickname per RBridge, per port per RBridge and per VLAN
   per RBridge. The operating status includes the information of LSDB,
   unicast and multicast routing table, RPF check, nickname, peer and
   some statistics.
   The figure below describe the overall structure of the TRILL Yang
   model:

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.

6. IANA Considerations

   This document requires no IANA Actions. RFC Editor: Please remove
   this section before publication.
