For years, many network engineers and designers have ignored IPv6. They designated it as something they’d get to “someday”. But now they’ve run out of time to kick that can down the road. Read More

This post helps to celebrate the upcoming 3-Day IPv6 Bootcamp here at INE. We always hear much excitement regarding the stateless address autoconfiguration capability in IPv6, but we never seem to get to see it in action. And also, we realize that one router can provide another with the address information it needs, but what about things like DNS server information? In this demonstration I will show how the stateless autoconfiguration can be setup, as well as a nifty stateless DHCPv6... Read More

IPv6 multicast renames IGMP to the Multicast Listener Discovery Protocol (MLP). Version 1 of MLD is similar to IGMP Version 2, while Version 2 of MLD is similar to Version 3 IGMP. As such, MLD Version 2 supports Source Specific Multicast (SSM) for IPv6 environments. Using MLD, hosts can indicate they want to receive multicast transmissions for select groups. Routers (queriers) can control the flow of multicast in the network through the use of MLD. Read More

IPv6 multicast is an important new blueprint topic for the Version 4.X CCIE R&S Lab Exam as well as the Written Qualification Exam. In this post, we will start at the most logical starting point for this topic - the IPv6 multicast addressing in use. Like in IP version 4, multicast refers to addressing nodes so that a copy of data will be sent to all nodes that possess the address. Multicast allows for the elimination of broadcasts in IPv6. Broadcasts in IP version 4 were problematic, since the... Read More

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 More

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 More
