An Introduction to IPv6 Tunneling
Tunneling mechanisms can be used to deploy an IPv6 forwarding infrastructure while the overall
IPv4 infrastructure is still the basis, because it either should not, or cannot be modified or upgraded.
Tunneling is also called encapsulation. With encapsulation, IPv6 protocol is encapsulated in the
header of IPv4 protocol and forwarded over the infrastructure of the IPv4 protocol. Tunnels can be
configured in a host or a router, however, each tunnel endpoint must support dual stack. In this
device IPv6 supports the following types of tunneling mechanisms:
1)
Manual
2)
6to4 (base on RFC 3056, but not support relay function)
3)

IPv6 Manually Configured Tunnel
A manually configured tunnel is a permanent link between two IPv6 networks over an IPv4 infrastructure. The major
use is for stable connections that require regular communication between two dual stack endpoints. An IPv6
address is manually configured on a tunnel interface, and manually configured IPv4 addresses are assigned to the
tunnel source and the tunnel destination.
