1. Introduction
Dual-Stack Lite [RFC6333] is a solution that offers both IPv4 and
IPv6 connectivity to customers crossing an IPv6-only infrastructure.
One of its key components is an IPv4-over-IPv6 tunnel, which is used
to provide IPv4 connectivity across a service provider's IPv6
network. Another key component is a carrier-grade IPv4-IPv4 Network
Address Translation (NAT) to share service provider IPv4 addresses
among customers.
This document defines a portion of the Management Information Base
(MIB) for use with network management protocols in the Internet
community. This MIB module may be used for configuration and
monitoring of Address Family Transition Routers (AFTRs) in a Dual-
Stack Lite scenario.
