About This Network Configuration Example


This document describes how service providers can implement IPv4 and IPv6 dual stack in a Point-to-Point Protocol over Ethernet (PPPoE) subscriber access network. It also provides a step-by-step configuration example for configuring a dual stack that uses Neighbor Discovery Router Advertisement (NDRA) and Dynamic Host Configuration Protocol for IPv6 (DHCPv6) prefix delegation over PPPoE. You learn how to add two types of IPv6 addressing to your subscriber network, and then how to create a dual stack implementation that uses these types of addressing. This document assumes that you already have IPv4 running in your network.
