In Figure 9–3, 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 IPv4 packet and routes the IPv6 packet to host A. For

hosts, the host-to-router tunnel is more efficient because the host I administrator

does not need to create individual host-to-host tunnels for each destination host.
