It is time now for us to wrap up this series on IPv6 transition techniques (in the scope of the R&S CCIE Written and Lab exam). For this final part, we turn to an existing blog post from our own resident genius, Petr Lapukhov. I edited his post to ensure we mere mortals could understand it. [Read the rest of this entry -->]

For those of you that have been following the previous parts of this blog series (they are located in the IPv6 subcategory of the CCIE R&S category to the left), get ready for a major paradigm shift. So far, we have been experimenting with transition techniques (tunnels) that have focused on connecting remote “island” networks of IPv6 over an IPv4-only infrastructure. Now we are going to discuss a mechanism that was designed to help IPv4-only hosts communicate to other native IPv6 devices.... [Read the rest of this entry -->]

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 islands of IPv6 want to communicate over an IPv4-only backbone. We know that many different tunnels exist for this purpose. For more information about these tunnel techniques, see the Transition Technique series in this blog category.... [Read the rest of this entry -->]
