Test Setup for Dual-Stack Router Providing IPv6 Connectivity via 6to4 Tunnels Over the IPv4 WAN

3 min read

What is dual-stack? Dual-stack CPE devices typically enable IPv6 connectivity via native IPv6 connections on the WAN or via tunneling protocols that transmit encapsulated IPv6 packets over the IPv4 WAN. Protocols such as DHCPv6 (with and without prefix delegation), PPPoE (running DHCPv6 or autoconf for address resolution), autoconf, or static IPv6 addressing can be used to provide native IPv6 connectivity on the WAN, whereas the most common tunneling protocols are 6to4 and 6rd.
