Configuring a tunnel for IPv6 VLANs to communicate through an IPv4 network

Use the following procedure to configure a tunnel for IPv6 VLANs to communicate through an IPv4 network. Manual tunnels are point-to-point, so you configure both source and destination addresses. You must configure both IPv6 and IPv4 addresses for both source and destination devices. The IPv6 addresses must represent the same network, for example 6666::1/96 and 6666::2/96.
