-As shown in Figure 1, we suppose that your lab is equipped with either dual-stack (supporting IPv4 and IPv6) devices or IPv6-only devices. In order to get IPv6 connectivity to your lab, you need to traverse a legacy IPv4-only network. Unfortunately, this is still the case for many Internet Service Providers around the world.
+As shown in Figure 1, we suppose that your lab is equipped with either dual-stack (supporting IPv4 and IPv6) devices or IPv6-only devices. We also suppose that you have no direct Internet IPv6 connectivity since you need to traverse a legacy IPv4-only access network. Unfortunately, this is still the case for many Internet Service Providers around the world.
-In such case, tunnel mechanisms can help you get IPv6 connectivity without waiting for the migration of the IPv4-only network. [[https://tools.ietf.org/rfc/rfc7059.txt | RFC 7059]] presents an exhaustive overview of tunnel mechanisms. In this document, you will use a static 6in4 tunnel. Precisely, IPv6 packets generated by your lab devices are encapsulated in IPv4 headers in order to traverse the IPv4-only network. This IPv4 header is removed, and the original IPv6 packets are routed on the dual-stack Internet. The incoming packets undergo a similar process to reach your lab devices.
