9.3.2 Intranet-to-Internet Scenario

In this scenario, you add a v4/v6 router to your network and use it to communicate

with the global Internet. The IPv6 hosts communicate with the v4/v6 router using

IPv6. For IPv6 traffic to v4/v6 hosts on the 6bone or the Internet, you configure

router-to-host tunnels.

Figure 9–4 illustrates a scenario in which the corporation described in the chapter

adds a connection from router A to the Internet. Potential destination nodes are in

turn connected to the Internet.

In Figure 9–4, to communicate with host J, host A sends the IPv6 packet to router

A. Router A encapsulates the IPv6 packet and sends the IPv4 packet over a

router-to-host tunnel to host J, which decapsulates the IPv4 packet.
