The document discusses IPv6 addressing, software versions, and topology issues for campus networks. It recommends using a /48 address block and sequentially assigning the remaining 16 bits for subnets. Router software like JUNOS 5.1 and IOS 12.2T and later provide line-rate IPv6 support. Topology designs include layer 2 and 3 campus options with IPv6 routers and dual-stack hosts. The document also covers DNS, equipment needs, and a lack of IPv6 traffic on networks.
