There are many test IPv6 networks deployed across the world. For actual deployment, however, all the companies need to ensure that the vendors who support companys network have the requisite IPv6 enhancements. There are two categories of IPv6 enhancements. The first is the set that supports the packet forwarding (more commonly referred to as routing) process and the other set comprises enhancements that support the computing or host infrastructure. IPv6 enhancements of the first category include larger address formats (the ones that affect the routing table size and structure), better routing protocols such as Open Shortest First Protocol (OSPF) and Routing Information Protocol (RIP), and good support for optional extension headers (which streamline the packet forwarding process) such as the Routing Header. And, the second category of enhancements comprises enhancements to the Domain Name System (DNS), the Stateless Auto-configuration (plug and play) process, upgraded Security, and updates to the Application Programming Interfaces (APIs). Keeping these requisite enhancements in mind, let us now discuss what kind of support ten of the premier networking vendors are equipped to provide: Solution There are many test IPv6 networks deployed across the world.
