Example “6to4” Topology
Figure 6-2 shows two IPv6 subnetworks. The end nodes have their
routers globally unique IPv4 addresses embedded in their network
prefixes. The routers have “6to4” addresses and corresponding globally
unique IPv4 addresses. From the IPv6 end-node view, each host’s
subnetwork is connected to the other’s through a 6to4 router. All IPv4
tunneling is transparent to the IPv6 end nodes.
