              Common YANG Data Types for the Routing Area

Abstract

   This document defines a collection of common data types using the
   YANG data modeling language.  These derived common types are designed
   to be imported by other modules defined in the routing area.

RFC 8294                 Routing Area YANG Types           December 2017

1.  Introduction

   YANG [RFC6020] [RFC7950] is a data modeling language used to model
   configuration data, state data, Remote Procedure Calls, and
   notifications for network management protocols.  The YANG language
   supports a small set of built-in data types and provides mechanisms
   to derive other types from the built-in types.

   This document introduces a collection of common data types derived
   from the built-in YANG data types.  The derived types are designed to
   be the common types applicable for modeling in the routing area.

1.1.  Terminology

   The terminology for describing YANG data models is found in
   [RFC7950].

2.  Overview

   This document defines two YANG modules for common routing types:
   ietf-routing-types and iana-routing-types.  The only module imports
   (ietf-yang-types and ietf-inet-types; see Section 3) are from
   [RFC6991].  The ietf-routing-types module contains common routing
   types other than those corresponding directly to IANA mappings.
   These include the following:

   router-id
      Router Identifiers are commonly used to identify nodes in routing
      and other control-plane protocols.  An example usage of router-id
      can be found in [OSPF-YANG].

   route-target
      Route Targets (RTs) are commonly used to control the distribution
      of Virtual Routing and Forwarding (VRF) information (see
