CDRouter IPv6 User Guide 6.3/Introduction

Introduction
CDRouter IPv6 adds IPv6 test capabilities to our industry leading CPE and router test platform, CDRouter. CDRouter IPv6 has been designed from the ground up to support the most common IPv6 features found in today’s leading IPv4/IPv6 dual-stack CPE implementations.
CDRouter IPv6 supports dual-stack CPE devices that implement the following IPv6 WAN connection modes:
- Static IPv6, optionally with RFC 3633 prefix delegation
- RFC 3315 DHCPv6, optionally with RFC 3633 prefix delegation
- RFC 4862 stateless address autoconfiguration, optionally with RFC 3633 prefix delegation
- RFC 3056, commonly referred to as “6to4” tunneling
- RFC 5969, commonly referred to as “6rd” tunneling
- RFC 5072 IPv6 over PPPoE, with static LAN configuration or DHCPv6
- Support for additional IPv6 WAN modes may be included in future releases
RFC 3056 and RFC 5969 are commonly referred to as “6to4” and “6rd”, respectively, and are similar techniques for providing automatic IPv6 connectivity over IPv4 networks. Although drafted first, 6to4 is operationally a subset of 6rd by utilizing a fixed prefix length and globally accessible relay servers.
When CDRouter IPv6 is enabled, CDRouter will create and maintain the necessary IPv6 next-hop gateway or relay server on the WAN. CDRouter will also create one or more IPv6 clients on the LAN that support either RFC 3315 DHCPv6 or IPv6 stateless address autoconfiguration as defined in RFC 4862.
CDRouter IPv6 is compatible with all CDRouter or CDRouter Multiport test setups and can be enabled on any existing CDRouter or CDRouter Multiport license. Before IPv6 testing can begin, the license file must be updated to enable CDRouter IPv6. See the Requirements and License section of this document for more information on enabling IPv6.
Once you have enabled IPv6 support within CDRouter, you can select and run any of the IPv6 specific test modules included with CDRouter IPv6. The IPv6 test modules can be run either individually or as part of a larger test run which includes other CDRouter, CDRouter Multiport, CDRouter IKE, or CDRouter TR-069 test modules.
Like all products in the CDRouter family, CDRouter IPv6 creates all of the necessary WAN-side and LAN-side network elements required to completely simulate an end-to-end IPv6 network within a single test system. CDRouter IPv6 allows the user to easily and efficiently create a variety of IPv6 network scenarios and utilize the array of included functional verification tests to thoroughly explore the IPv6 behavior of the device under test (DUT).
