C has OSPF correctly set up on all the interfaces. The area range command only works on an ABR. We don't see R1 is any indication of ABR in this case, and area range command does nothing. In my lab even when I make R1 an ABR by adding a loopback: interface Loopback0 ip address 1.1.1.1 255.255.255.0 ipv6 enable ospfv3 1 ipv4 area 0 The 192.168.1.0 isn't summarized on R2 or R3 when I use "C" because the LSA isn't going through Area 0. B = Answer
