Testing 6to4 and 6rd IPv6 Islands with CDRouter

The world has spent a long time on the road to native IPv6. Fortunately, protocol advancements have mitigated the arduous task of deploying the next generation Internet. Essentially the software counterpart to the last-mile problem, deploying IPv6 to the CPE is “the last 90%” of the work. The core Service Provider networks have always been easier, and thus earlier, to receive both hardware and software upgrades. One idea that has gained momentum is to use the IPv4 Internet as a point-to-point network connecting IPv6 “islands” through stateless, automatic tunnels. Read more...

Testing dual-stack lite (DS-Lite) B4 CPE devices

CDRouter makes it easy to test dual-stack lite B4 CPE implementations on a functional level, and when combined with the many LAN modes of operation available, can help identify issues that are not visible by iterative conformance testing. Dealing with IPv6 transitioning Many IPv6 transition strategies have been provided. Some, such as 6to4, have been available to end users for years now, since ISPs have no prerequisite of IPv6 routing to support the 6to4 protocol. Read more...
