The correct answer is B. Design the OSPF backbone to be area 0 and aggregate routes between them. See the full explanation below for the reasoning.
Question
The routing switches shown in the exhibit use OSPF, and all of their interfaces are in Area 1. A faulty link on Switch-1 went up and down many times over the course of several hours, which generated many unstable routing entries in the OSPF routing process of the affected Area 1 and the backbone. The network administrator fixed the faulty link on Switch-1, but the administrator also wants to mitigate the effects if a similar issue occurs in the future. Which design improvement would help?
Options
- AConfigure Area 1 as a stub area on all routers except Switch-2, Switch-3, and Switch-4
- BDesign the OSPF backbone to be area 0 and aggregate routes between them
- CDivide the AS into different areas, and configure the backbone area as an NSSA
- DDecrease the LSA generation timer, and make sure to set the same value on all routers
