Internet-Draft        IANA AFN and SAFI YANG Module            July 2013


1.  Introduction

   This document defines the initial version of the iana-afn-safi YANG
   module, for Address Family Numbers (AFN) and Subsequent Address
   Family Identifiers (SAFI).

   The iana-afn-safi module reflects IANA's existing "Address Family
   Numbers" and "SAFI Values" registries.

   Whenever a new address family number is added to the "Address Family
   Numbers" registry, the IANA-ADDRESS-FAMILY-NUMBERS-MIB and the iana-
   afn-safi YANG module are updated by IANA.

   Whenever a new subsequent address family identifier is added to the
   "SAFI Values" registry, the iana-afn-safi YANG module is updated by
   IANA.

3.  IANA Considerations

   This document defines the initial version of the IANA-maintained
   iana-afn-safi YANG module.

   IANA is requested to extend the registries "Address Family Numbers"
   and "SAFI Values" with a "Name" column.  IANA is also requested to
   add this new Note to these registries:

     The name of an entry in this registry must be a legal SMIv2
     enumeration label.

   The existing entries in the "Address Family Numbers" registry should
   get their names from the corresponding "enum" statement in the
   "address-family" typedef.

   The existing entries in the "SAFI Values" registry should get their
   names from the corresponding "enum" statement in the
   "subsequent-address-family" typedef.

   The iana-afn-safi module is intended to reflect the "Address Family
   Numbers" and "SAFI Values" registries.  When an AFN or SAFI is added
   to these registries, a new "enum" statement must be added to the
   "address-family" or "subsequent-address-family" typedefs.  The name
   of the "enum" is the value of the "Name" column in the registry.

   The following substatements to the "enum" statement should be
   defined:

     "value": Replicate the value from the registry.

     "status": Include only if a registration has been deprecated (use
               the value "deprecated") or obsoleted (use the value
               "obsolete").

     "description": Replicate the description from the registry, if any.

     "reference": Replicate the reference from the registry, if any, and
                  add the title of the document.

   If a parameter is marked as "reserved" in these registries, no "enum"
   statement is added to the corresponding typedef.  Instead a comment
   is added, on the form:

     // value NN is reserved by XX

   Unassigned values are not present in the module.

Internet-Draft        IANA AFN and SAFI YANG Module            July 2013


   When the iana-afn-safi YANG module is updated, a new "revision"
   statement must be added.

   IANA is requested to add this new Note to the "Address Family
   Numbers" and "SAFI Values" registries:

     When this registry is modified, the YANG module iana-afn-safi
     must be updated as defined in RFC XXXX.

   The Reference text in the "Address Family Numbers" registry needs to
   be updated as:

     OLD:
       [RFC2453][RFC2858]

     NEW:
       [RFC2453][RFC2858][RFCXXXX]

   The Reference text in the "SAFI Values" registry needs to be updated
   as:

     OLD:
       [RFC4760]

     NEW:
       [RFC4760][RFCXXXX]

3.1.  URI Registrations

   This document registers a URI in the IETF XML registry [RFC3688].
   Following the format in RFC 3688, the following registration is
   requested to be made.

        URI: urn:ietf:params:xml:ns:yang:iana-afn-safi

        Registrant Contact: IANA.

        XML: N/A, the requested URI is an XML namespace.

3.2.  YANG Module Registrations

   This document registers a YANG module in the YANG Module Names
   registry [RFC6020].

     name:         iana-afn-safi
     namespace:    urn:ietf:params:xml:ns:yang:iana-afn-safi
     prefix:       ianaaf
     reference:    RFC XXXX

4.  Security Considerations

   Since this document does not introduce any technology or protocol,
   there are no security issues to be considered for this document
   itself.
