3 The traffic routed to the 6to4 tunnel interface is then encapsulated into IPv4 headers and sent to the
destination 6to4 router over the IPv4 domain.
destination 6to4 router over the IPv4 domain.
4 The destination 6to4 router strips the IPv4 header and forwards it to the IPv6 destination host.

tion and scenarios by using 6to4 tunnels, refer to RFC 3056.
Configured Tunnels
A configured tunnel is where the endpoint addresses are manually configured to create a point-to-point
tunnel. This type of tunnel is similar to the 6to4 tunnel on which IPv6 packets are encapsulated in IPv4
headers to facilitate communication over an IPv4 network. The difference between the two types of
tunnels is that configured tunnel endpoints require manual configuration, whereas 6to4 tunneling relies on
an embedded IPv4 destination address to identify tunnel endpoints.

2893 also discusses automatic tunnels, which are not supported with this implementation of IPv6.
