Like OSPFv2, OSPFv3 provides similar OSPFv3 verification commands. Refer to the reference OSPFv3 topology in Figure 1.
Figure 2 displays the OSPFv3 settings of R1. Notice that the command confirms that there are now two areas. It also identifies each interface enabled for the respective area.
Figure 3 verifies the OSPFv3-enabled interfaces and the area to which they belong.
Figure 4 displays the routing table of R1. Notice how the IPv6 routing table displays OI entries in the routing table to identify networks learned from other areas. Specifically, O represents OSPF routes, and I represents interarea, which means that the route originated from another area. Recall that R1 is in area 0, and the 2001:DB8:CAFE3::/64 subnet is connected to R3 in area 2. The [110/1295] entry in the routing table represents the administrative distance that is assigned to OSPF (110) and the total cost of the routes (cost of 1295).
Figure 5 displays the content of the LSDB of R1. The command offers similar information to its OSPFv2 counterpart. However, the OSPFv3 LSDB contains additional LSA types not available in OSPFv2.
