1.  Introduction

   This document specifies the initial version of an IANA-maintained
   module to identify a collection of tunnel types assigned by IANA
   (Section 2).  Furthermore, the document augments the Interface YANG
   module [RFC8343] with a new parameter which is meant to indicate the
   type of a given tunnel (Section 3).  The tree structure of this
   extension is shown below:

   module: ietf-interface-tunnel
     augment /if:interfaces/if:interface:
       +--rw tunnel-type?   identityref

   Tunnel-specific extensions may be added to the Interface module as a
   function of the tunnel type.  A sample example is provided in
   Appendix A.  It is not the intent of this document to define tunnel-
   specific extension for every tunnel encapsulation technology; those
   are discussed in dedicated document such as [I-D.ietf-softwire-yang].

Internet-Draft  Tunnel Extension to the Interface Module    October 2018

   This document uses the common YANG types defined in [RFC6991] and
   adopts the Network Management Datastore Architecture (NMDA).

   The terminology for describing YANG modules is defined in [RFC7950].
   The meaning of the symbols in tree diagrams is defined in [RFC8340].
