Here's an OSPF topology question which answer I don't understand. Based on the "debug ip ospf events" command we see an area mismatch. The topology indicates that Router C has both interfaces in Area 0. Router A & Router B are both ABRs and it would seem that to resolve the issue you would place both routers E0/0 interfaces in Area 0. But the correct answer is "Configure the E0/1 interfaces of router A and router B to be in area 0." It seems to me that would cause a discontiguous Area 0 link.
