For Part 1 of this series on IPv6 Transition Mechanisms, click here. If you loved the simplicity of the IPv6 manual tunnel we created in Part 1, you should love the Generic Routing Encapsulation (GRE) approach to tunneling IPv6 traffic through an IPv4 cloud just as much. This simple approach takes the IPv6 packet and encapsulates it using the standard IPv4 GRE tunnel. But wait a minute? In Part 1 of this blog series, we had IPv4 encapsulate the IPv6 packet directly for tunneling across the v4... Read More

This blog series was recommended by another of our awesome students and IEOC community members, Marcio A. Costa. In the first part of this series, we will look at the Manual IPv6 tunnels that are simple to create in order to connect two "islands" of IPv6 separated by IPv4-only devices. For this blog, we will use the following simple topology: Read More

The IPv6 section for IEWB-RS Volume 1 Version 5.0 is now posted on the members site. This leaves only BGP and Multicast left for completion, which are both currently in development. More information will be posted on those shortly. The following sections are available for IPv6: IPv6 Link-Local Addressing IPv6 Unique Local Addressing IPv6 Global Aggregatable Addressing Read More

IPv6 NAT-PT is to be used with IPv4 to IPv6 migration scenarios and it's purpose is to provide bi-directional connectivity between IPv4 and IPv6 domains. Cisco points out that many other transition techniques are possible, and NAT-PT (Network Address Translation - Protocol Translation) should not be used when other, more "native" options exist, such as having dual stack hosts communicate directly through dual stack routers. Another example provided of when NAT-PT is not needed is when two... Read More
