IPv4 and IPv6 will coexist for some time.A wide range of techniques are available for the period of transition between IPv4 and IPv6. These techniques can be grouped into three categories:Dual-stack techniquesTunneling servicesTranslation servicesThis presentation will describe the configuration of transition mechanisms and provide sample topologies and configuration commands.The techniques covered will include: dual-stack, manual tunnels, 6to4 tunnels, ISATAP tunnels and NAT-PT.Note: NAT-PT has been moved to historical status with RFC 4966.
Benefits Native dual-stack does not require any tunneling mechanisms on internal networks.Both IPv4 and IPv6 run independent of each other.Dual stack supports gradual migration of endpoints, networks, and applications.
