Enterprise IPv6 Transition Strategy
Government mandates, e-business and Internet growth requirements, and impending IPv4 address exhaustion concerns are prompting many enterprises to begin implementing an IPv6 transition strategy. The available techniques for supporting IPv6 transition strategies fall into three categories: IPv6 native (dual-stack), IPv6 tunneling, and IPv6 translation. Most of these techniques have limited capabilities, or are difficult or have constraints in deployment. The Locator/ID Separation Protocol (LISP) implements a new routing architecture that is designed for a much broader purpose than IPv6 transition. LISP was designed to be address family agnostic, and when incorporated LISP into an IPv6 transition strategy, LISP has demonstrated quick deployment time, low deployment and operational cost, little or no need for additional equipment or modifications, and high user-satisfaction.
