Intranet Scenario

To communicate with Host I, Host A sends an IPv6 packet to Router A. Router A

forwards the IPv6 packet to Router B. Router B encapsulates the IPv6 packet and

sends the IPv4 packet over a router-to-host tunnel to Host I, which decapsulates the

IPv4 packet. The IPv4 infrastructure routes the packet to Host I.

To communicate with Host A, Host I encapsulates the IPv6 packet and sends the IPv4

packet over a host-to-router tunnel to Router B. From there, Router B decapsulates the
