                      draft-ietf-softwire-yang-15

Abstract

   This document defines YANG modules for the configuration and
   operation of IPv4-in-IPv6 softwire Border Relays and Customer
   Premises Equipment for the Lightweight 4over6, Mapping of Address and
   Port with Encapsulation (MAP-E), and Mapping of Address and Port
   using Translation (MAP-T) softwire mechanisms.

Editorial Note (To be removed by RFC Editor)
