In the topology in Figure 1, all of the routers have been configured to support OSPFv3 routing.

A quick look at the R1 IPv6 routing table (Figure 2) reveals that it receives the default route, the R2 LAN (2001:DB8:CAFE:2::/64) and the link between R2 and R3 (2001:DB8:CAFE:A002::/64). However, it does not receive the R3 LAN OSPFv3 route (2001:DB8:CAFE:3::/64).

The output in Figure 3 verifies the OSPFv3 settings on R3. Notice that OSPF is only enabled on the Serial 0/0/1 interface. It appears that it is not enabled on the G0/0 R3 interface.

Unlike OSPFv2, OSPFV3 does not use the network command. Instead OSPFv3 is enabled directly on the interface. The output in Figure 4 confirms that the R3 interface is not enabled for OSPFv3.

The example in Figure 5 enables OSPFv3 on the R3 Gigabit Ethernet 0/0 interface. R3 should now advertise the R3 LAN to its OSPFv3 neighbors.

The output in Figure 6 verifies that the R3 LAN is now in the routing table of R1.
