The purpose of this document is to provide an in-depth overview of deployment considerations for IPv6 using the Catalyst 6500 platform. The new Supervisor 2T provides capabilities that support next-generation IPv6 networks, and this document will cover some of those capabilities. It is not the intent of this document to provide an IPv6 tutorial or a thorough exploration of IPv6 protocols.
As companies grow in the future, their network needs will also grow. Tomorrow's networks will grow in the IPv6 space. Today's IPv4 networks will have limited future growth. Some companies are already running out of IPv4 address space and are reallocating their existing pool. Internationally outside the US, IPv4 addresses are in even shorter supply. The Catalyst 6500 Supervisor 2T is designed for IPv6 networking. Enhancements for IPv6 were added to Supervisor 2T that are not available on previous generation hardware. There are several drivers in addition to the lack of new IPv4 address space. One of the reasons is to be compliant with US Government certifications in the public sector. Others reasons for IPv6 are to use new IPv6 only applications. IPv6 pilot deployments are not disruptive to existing IPv4 networks. There are many new transition technologies that are available on the Supervisor 2T to make an IPv6 dual stack topology or migration work.

This is a perfect companion to the Cisco Cloud Security Accelerates Cloud Adoption paper published earlier this month.
Just as noted with that paper, "And don't be fooled by the fact that this focuses on Cisco. The first half of the paper is generic and does a great job of addressing various points that must be addressed. And even though the second half of the paper addresses Cisco's solutions, it provides a great benchmark regardless of your exact choice of provider."
Again, very highly recommended.
