Tunnel Interface Types YANG Module
draft-ietf-softwire-iftunnel-07
Abstract
This document specifies the initial version of a YANG module
containing a collection of IANA maintained YANG identities, used as
interface types for tunnel interfaces. The module reflects the
"tunnelType" registry maintained by IANA. The latest revision of
this YANG module can be obtained from the IANA web site.
Tunnel type values are not directly added to the Tunnel Interface
Types YANG module; they must instead be added to the "tunnelType"
IANA registry. Once a new tunnel type registration is made by IANA
for a new tunneling scheme or even an existing one that is not
already listed in the current registry (e.g., LISP, NSH), IANA will
update the Tunnel Interface Types YANG module accordingly.
Some of the IETF-defined tunneling techniques are not listed in the
current IANA registry. It is not the intent of this document to
update the existing IANA registry with a comprehensive list of tunnel
technologies. Registrants must follow the IETF registration
procedure for interface types whenever a new tunnel type is needed.
Editorial Note (To be removed by RFC Editor)
Please update these statements in the document with the RFC number to
be assigned to this document:
o "This version of this YANG module is part of RFC XXXX;"
o "RFC XXXX: Tunnel Interface Types YANG Module";
o "reference: RFC XXXX"
o "...must be updated as defined in RFCXXXX."
Please update the "revision" date of the YANG modules.

Internet-Draft Tunnel Interface Types June 2019
1. Introduction
This document specifies the initial version of the iana-tunnel-type
YANG module containing a collection of IANA maintained YANG
identities identifying tunnel interface types. The module reflects
IANA's registry maintained at [TUNNELTYPE-IANA-REGISTRY]. The latest
revision of this module can be obtained from the IANA web site.
Tunnel-specific extensions may be added to the Interface module
[RFC8343] as a function of the tunnel type. An example of this is
provided in Appendix A. It is not the intention of this document to
define tunnel-specific extensions for every tunnel encapsulation
technology; those are discussed in dedicated documents such as
[I-D.ietf-softwire-yang]. Likewise, it is out of the scope of this
document to update the existing IANA registry
[TUNNELTYPE-IANA-REGISTRY] with a comprehensive list of tunnel
technologies. Guidelines and registration procedures for interface
types and sub-types are discussed in [I-D.thaler-iftype-reg].
This document uses the common YANG types defined in [RFC6991] and
adopts the Network Management Datastore Architecture (NMDA
[RFC8342]).
The terminology for describing YANG modules is defined in [RFC7950].
The meanings of the symbols used in the tree diagram are defined in
[RFC8340].
2. IANA Tunnel Type YANG Module
The iana-tunnel-type module imports the 'iana-if-type' module defined
in [RFC7224].
The initial version of the module includes tunnel types defined in
[RFC4087], [RFC7856], [RFC7870], and [RFC6346].

3. Security Considerations
The YANG module specified in this document defines a schema for data
that is designed to be accessed via network management protocols such
as NETCONF [RFC6241] or RESTCONF [RFC8040]. The lowest NETCONF layer
is the secure transport layer, and the mandatory-to-implement secure
transport is Secure Shell (SSH) [RFC6242]. The lowest RESTCONF layer
is HTTPS, and the mandatory-to-implement secure transport is TLS
[RFC8446].
The Network Configuration Access Control Model (NACM) [RFC8341]
provides the means to restrict access for particular NETCONF or
RESTCONF users to a preconfigured subset of all available NETCONF or
RESTCONF protocol operations and content.

Internet-Draft Tunnel Interface Types June 2019
The module defined in this document defines YANG identities for the
iana-tunnel-types registry. These identities are intended to be
referenced by other YANG modules, and by themselves do not expose any
nodes which are writable, contain read-only state, or RPCs. As such,
there are no additional security issues to be considered relating to
the module defined in this document.
4. IANA Considerations
4.1. YANG Module
This document requests IANA to register the following URI in the "ns"
subregistry within the "IETF XML Registry" [RFC3688]:
URI: urn:ietf:params:xml:ns:yang:iana-tunnel-type
Registrant Contact: IANA.
XML: N/A; the requested URI is an XML namespace.
This document requests IANA to register the following following YANG
module in the "YANG Module Names" subregistry [RFC7950] within the
"YANG Parameters" registry.
Name: iana-tunnel-type
Namespace: urn:ietf:params:xml:ns:yang:iana-tunnel-type
Prefix: iana-tunnel-type
Reference: RFC XXXX
This document defines the initial version of the IANA-maintained
iana-tunnel-type YANG module. IANA is requested to add this note:
Tunnel type values must not be directly added to the iana-tunnel-
type YANG module. They must instead be respectively added to the
"tunnelType" sub-registry (under the "ifType definitions"
registry).
When a tunnel type is added to the "tunnelType" sub-registry, a new
"identity" statement must be added to the iana-tunnel-type YANG
module. The name of the "identity" is the lower-case of the
corresponding enumeration in the IANAifType-MIB (i.e.,
IANAtunnelType). The "identity" statement should have the following
sub-statements defined:
"base": Contains 'ift:tunnel'.
"description": Replicates the description from the registry.
"reference": Replicates the reference from the registry and add the
title of the document.

Internet-Draft Tunnel Interface Types June 2019
Unassigned or reserved values are not present in the module.
When the iana-tunnel-type YANG module is updated, a new "revision"
statement must be added in front of the existing revision statements.
IANA is requested to add this note to "tunnelType" sub-registry:
When this registry is modified, the YANG module iana-tunnel-type
must be updated as defined in RFCXXXX.

[RFC8343] Bjorklund, M., "A YANG Data Model for Interface
Management", RFC 8343, DOI 10.17487/RFC8343, March 2018,
<https://www.rfc-editor.org/info/rfc8343>.
Appendix A. Example Usage
The following example illustrates how the Interface YANG module can
be augmented with tunnel-specific parameters. In this example, the
module is augmented with a 'remote-endpoint' for the tunnel. A tree
structure is provided below:
module: example-iftunnel-extension
augment /if:interfaces/if:interface:
+--rw remote-endpoint? inet:ipv6-address
The 'example-iftunnel-extension' module imports the modules defined
in [RFC6991] and [RFC8343] in addition to the "iana-tunnel-type"
module defined in this document.
module example-iftunnel-extension {
yang-version 1.1;
namespace "urn:ietf:params:xml:ns:yang:example-iftunnel-extension";
prefix example;
import ietf-inet-types {
prefix inet;
reference
"Section 4 of RFC 6991";
}
import ietf-interfaces {
prefix if;
