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 data model for the configuration of shorter srv6.

   [I-D.mirsky-6man-unified-id-sr] proposed an extension of SRH that
   enables the use of a shorter segment identifier, such as 32-bits
   Label format SID or 32-bits IP address format SID.

   [I-D.raza-spring-srv6-yang]introduces a YANG data model for base SRv6
   and SRv6 Static application.

   This document is to define the YANG data model for shorter srv6(
   Compressing SRv6 )

2.  Shorter SRv6 Types

   The Shorter-SRv6-Types augment "ietf-srv6-types"
   [I-D.raza-spring-srv6-yang], and defines new srv6-endpoint-type: SRv6
   Endpoint behaviors identity type.

3.  Configuration

3.1.  Shorter SRv6 base

   The Shorter-SRv6-base configuration augments the SRv6-base locator
   tree [I-D.raza-spring-srv6-yang]"/rt:routing/rt:srv6", and defines
   new Parameters.

   Following is a simplified graphical tree representation of the data
   model for Shorter SRv6 base configuration.

     module: ietf-shorter-srv6-base
           augment /rt:routing/rt:srv6:
            +--rw shorter-srv6
               +--rw node-capabilities
                      +--rw UET-support?             enumeration

       augment /rt:routing/rt:srv6/rt:locators/rt:locator/rt:prefix:
            +--rw lb-length     srv6-types:srv6-lb-len

3.2.  Shorter SRv6 Static

   The Shorter-SRv6-Static configuration augments the SRv6-base locator
   tree "/rt:routing/srv6:srv6/srv6:locators/srv6:locator/rt:prefix:",
   and defines new Parameters.
