Connecting to Devices Supporting IPv6 Over IPv4

 

Tunneling

 

The switches covered by this guide can interoperate with IPv6/IPv4 devices

 

capable of tunneling IPv6 traffic across an IPv4 infrastructure. Some examples

 

include:

 

■ traffic between IPv6/IPv4 routers (router/router)

 

■ traffic between an IPv6/IPv4 router and an IPv6/IPv4 host capable of

 

tunneling (router/host)

 

 

N o t e

Tunneling requires an IPv6-capable router. A switch running software release

 

K.13.01 does not route or tunnel IPv6 traffic. To enable IPv6 traffic from the

 

switch to be routed or to be tunneled across an IPv4 network, it is necessary

 

to connect the switch to an appropriate IPv6-capable router. For more infor­

 

mation, refer to the documentation provided with the dual- stack (IPv4/IPv6)

 

routers you plan to use for this purpose.

 

IPv6 tunneling eases IPv6 deployment by maintaining compatibility with the

 

 

large existing base of IPv4 hosts and routers. Generally, the various IPv6

 

tunneling methods enable IPv6 hosts and routers to connect with other IPv6

 

hosts and routers over the existing IPv4 Internet.

 

Information Sources for Tunneling IPv6 Over IPv4

 

For more information on IPv6 routing and tunneling, refer to the documenta­

 

tion provided with the IPv6/IPv4 routing and tunneling-capable devices in your

 

network. Some other sources of information are:

 

■ RFC 2893: “Transition Mechanisms for IPv6 Hosts and Routers”

 

■ RFC 2401: “Security Architecture for the Internet Protocol”

 

■ RFC 2473: “Generic Packet Tunneling in IPv6 Specification”

 

■ RFC 2529: “Transmission of IPv6 via IPv4 Domains without Explicit

 

Tunnels”

 

■ RFC 3056: “Connection of IPv6 Domains Over IPv4 Clouds”
