At this point in time, there are not enough people with both IPv6 experience, and training skills, to provide you with IPv6 training in the same way that you earn a CCIE. Of course, router vendors can teach you how to configure their devices and they do provide a wealth of published material that covers some of the experience of IPv6 pioneers. However, we are just beginning to see significant deployment of IPv6 in the real world harsh operational conditions of the Internet. This is likely to raise any number of issues which were unknown to the people who wrote existing books and training materials.
You must make a committment to seek out the up-to-date experience of other people who are on the same journey as you, scaling up IPv6 to replace IPv4 in the Internet. A lot of this up-to-date material will be in published papers and conference presentations. We hope that you will share links to that material here.
There are about 200 papers and presentations on IPv6 available from the IPv6 Eprints Server.
The Defense Research and Engineering Network (DREN) has published an IPv6 Security Assessment.
Since IPv6 was first introduced, there have been many changes to the protocol with many RFCs updated or deprecated. Unfortunately, this means that some books have incorrect information, and even recent authors may have the wrong impression about how IPv6 should be implemented/deployed. Brian Carpenter from the IETF recommends these two books as containing the most up to date explanations of IPv6.
The 6DEPLOY project makes available about 25 tutorials in PDF format that cover a variety of IPv6 topics such as Multicast, Network Management, Addressing and so on.
There is an Internet draft available clarifying how the IPv6 subnet model differs from IPv4.
Here are a couple of articles about setting up a small-scale IPv6 test lab for educational purposes.
Here is a brief overview of the tools used to set up an IPv6 lab using virtual machines on a virtual network.
NetKit bills itself as the poor man's system to experiment with computer networking. Downloads are available.
Here is a Usenix paper on building a virtual IPv6 lab using UserMode Linux virtualization. UserMode Linux (UML) has been widely used to build virtual network lab environments.
If you have Cisco licences then you might want to use DynaGen, a front end for DynaMIPS, the Cisco emulator. DynaGen makes it easier to run multiple instances of simulated routers for lab training purposes. Here is the DynaGen tutorial.
Build an IPv6 Router on Linux with NAT-PT and use this between your home IPv6 PCs and your IPv4 Internet access connection. Although the IETF has deprecated NAT-PT to historical status, it does work and some people feel that it is superior to 6to4 Relay. The best way to find out is to experience both of them for yourself.
It's always better if you can get your employer to buy a full library of IPv6 books for you, but if you are trying to come up to speed on your own dime, you might want to read a free book on IPv6 and Internetworking with Cisco routers.
If you know of any other books that can be freely downloaded, please add them here.
There's a lot of generic IPv6 training out there, but here's a few worth highlighting:
ARIN maintains some IPv6 information on their V6-Info pages and they also run tutorials at their twice yearly meetings. Here is the Sunday V6 schedule for the Albuquerque meeting which will happen on the 14th of October. In between V6 day and the main ARIN meeting there will be a NANOG meeting. NANOG and ARIN have one joint conference per year like this.
APNIC has a nice wiki too:
