The overall goal is to evolve the centralised single router IPv6 test network to a well managed IPv6 pilot that can be renamed to a highly reliable production network later on. The best way to achieve this is to establish a dual-stack network that uses the currently existing IPv4 network infrastructure for both IPv4 and IPv6 likewise.

The brief sketch in the chapter above might give you a hint the University’s network is quite complex in its IPv4 structures and tries to serve complex needs. Taking into account that there is also a lot of old hardware in use, one can imagine that it is illusionary to add dual-stack to the whole network in one step.
