In OSPF, the area range command is used on the Area Border Router (ABR) to create summary routes, which is essential for consolidating routing information between areas. This process reduces the amount of routing information passed between areas, ensuring more efficient and manageable OSPF operation. Configuring the area range command on the ABR will address the reachability issues by properly summarizing routes for each area.
D is correct answer The area range command is used only with area border routers (ABRs). It is used to consolidate or summarize routes for an area. The result is that a single summary route is advertised to other areas by the ABR. Routing information is condensed at area boundaries. External to the area, a single route is advertised for each address range.
The correct answer is: D
All answers are wrong. A and C have invalid syntax. B is for ASBRs, not relevant here. D is the only command that makes sense, but that is the command that was already used to configure the summarization.
Answer should be: D. Configure the area range command on the ABR CORRECTLY
The question is stupid, but it is indeed D, as that is only thing that makes sense. Anyway, what a bad question.
D is correct
