Cisco: An IPv6 Campus of the Future
IPv6 as a protocol has been known for a while, but enterprises are beginning to understand the ways in which it can help them achieve their goals, improve efficiency and gain functionality that were hitherto unavailable.
When the IPv4 to IPv6 transition first took place, some Internet-scale companies enthusiastically adopted the technology. They built out their data centers as IPv6-only networks understanding the impending exhaustion of IPv4 addresses. Most other companies attempted to manage the transition by simply migrating from native IPv4 to a dual stack network for IPv6 compatibility. This, however, neither saved IPv4 addresses nor improved features and applications over IPv6. The logical next step for those companies and indeed the industry, in general, is to implement entire campuses as IPv6-only networks. The advantages include avoiding the maintenance of two protocol stacks, reduced OPEX, and, chiefly, no more dependency on IPv4 address. The IPv6 network is cleaner, faster and more secure thanks to a protocol redesigned to embrace encryption, favor targeted multicast over expensive broadcast communication and remove variable length subnets from routing.
Cisco has been one of the early pioneers in this space. From an implementation and adoption standpoint, we have taken it upon ourselves to start building an IPv6-only campus to demonstrate to our customers not just the criticality of this technology but also how exactly to manage the transition seamlessly.
