An IPv6 tunnel in 6to4 mode connects an isolated IPv6 domain (that is, an 6to4 island) over 

an IPv4 domain to remote IPv6 domains or to another 6to4 island. An IPv6 tunnel in 6to4 
mode is also called an automatic 6to4 tunnel. Unlike a 6in4 tunnel, which is a point-to-point 
tunnel, a 6to4 tunnel is a point-to-multipoint tunnel. In a 6to4 tunnel, the IPv6 tunnel 
destination is determined by the IPv4 address, which is extracted from IPv6 destination 
address with the prefix 2002::V4ADDR::/48.

A NETGEAR switch behaves as a 6to4 border router that connects 6to4 islands (in the 

following figure, Switch 1 and Switch 2) to an IPv6 domain (in the following figure, Switch 3). 
This means the following:

The NETGEAR switch forwards traffic from an IPv6 domain (with a non-2002:: address) to a 
6to4 island (with a 2002:: address) and the other way around. (In the following figure, this 
type of forwarding refers to the traffic between Switch 1 and Switch 3 and the traffic between 
Switch 2 and Switch 3).

The NETGEAR switch forwards traffic from one 6to4 island to another 6to4 island (in the 
following figure, the traffic between Switch 1 and Switch 2). 

The NETGEAR switch does not forward traffic from one IPv6 domain (with a 
non-2002:: address) to other IPv6 domain (also with a non-2002:: address).
