Deploy and Monitor IPv6 End to End
Introduction
This white paper is a reference guide for designing an IPv6-enabled network. Using Las Vegas InteropNet 2011 as
a real-life template, this paper navigates through emerging IPv6 framework, challenges, and design elements,
exemplifying an IPv4 and IPv6 dual-stack network.
At Interop 2011, Cisco was a primary sponsor of InteropNet, a high-speed network built in collaborative fashion by
innovative vendors and volunteer engineers, creating a completely interoperabl
e network using the industry’s most
innovative technology.
One of the main focuses at InteropNet 2011 was IPv6, the next-generation IP protocol designed to resolve
limitations of IPv4, for example, data security and maximum number of user addresses. Deploying IPv6 over
wireless, security, and network management creates many new challenges. However, successful end-to-end IPv6
deployment is achievable. Due to the wide array of IPv6-ready Cisco
®
technologies, InteropNet experienced zero
“severity one” issues, while providing continuous, dual-stack availability over the course of five days.
IPv6-Ready Technology
InteropNet’s core and distribution networks (see Figure 1)were designed
around the Cisco Catalyst
®
6500-E Series Switch. Using 80 GigE link
aggregation, the Cisco Catalyst 6500-E provides IPv4 and IPv6 multicast
forwarding in hardware (with aggregated bandwidth of 2 terabits/second)
providing high-quality voice and video enablement.
The Cisco Catalyst 4500-E with Supervisor Engine 7-E was used for
access layer connectivity, offering full line-rate IPv6 forwarding
performance at 125 million packets per second (pps).
