Overview Requirements for transition to an IPv6 network. Steps towards migration to an IPv6 network. Requirements for transition to an IPv6 network The IPv6 network should perform just as well as the IPv4 network. (ex. Enough memory) Network Management tools for IPv6 network. (ex. Cisco Works) No disruption in service. Read more…
