CHAPTER 1 GENERAL INFORMATION
SYSTEM OUTLINE
IPv6/IPv4 Tunneling
Tunneling is the function that the information of a protocol is encapsulated into the packet of an another protocol and transferred. Tunneling makes it possible to transfer data between networks having different protocols. A maximum of eight tunnels are available, of which one is an automatic tunnel, and reserved. Many of the present networks are created with IPv4 and, therefore, IPv6 networks will be separated by IPv4 networks. If you want to shift to an IPv6 network in a stepwise manner, you can set a tunnel for the communication between hosts.
An
By using an existing IPv4 network, you can shift smoothly to an IPv6 network.
