Figure 1 displays the network topology that is used to configure OSPFv3.

Figure 2 shows IPv6 unicast routing and the configuration of the global unicast addresses of R1, as identified in the reference topology. Assume that the interfaces of R2 and R3 have also been configured with their global unicast addresses, as identified in the referenced topology.

In this topology, none of the routers have IPv4 addresses configured. A network with router interfaces configured with IPv4 and IPv6 addresses is referred to as dual-stacked. A dual-stacked network can have OSPFv2 and OSPFv3 simultaneously-enabled.

Figure 3 displays the steps to configure basic OSPFv3 in a single area.
