If your IPv6 traffic needs to travel through IPv4 networks to reach its destination, you need to set
up a virtual link by configuring a tunnel.
To configure IPv6 in IPv4 tunnels

Configuration in the tree view.
2. Enter the IPv4 address of the local tunnel endpoint in the Local IPv4 Address text box.

Note
The local address must be the address of another interface configured for the router.

Link Local text box.
If you do not specify an address a default will be configured.
