Refer to the exhibit. An engineer is designing an OSPF solution with these requirements: - NMS server will manage R5 and R6. - Upon failure of R1, all NMS traffic should be routed through R4. - Upon…

By running two OSPF processes and redistributing routes between them on R1 and R4, path preferences can be controlled through metrics and administrative distance, enabling traffic to automatically failover to R4 if R1 or its primary paths fail, meeting the specific rerouting requirements.

Advertising a single IP with a high cost on R1 does not provide comprehensive rerouting for all NMS traffic or the specific destination 10.6.6.6 upon various failure scenarios.

Using static routes with IP SLA tracking on R2 and R3 would be overly complex to manage and scale for multiple failure conditions and specific destination routing requirements, compared to a dynamic OSPF solution.

Enabling `default-information originate` with a higher metric on R2 to R1 primarily controls default route advertisement, which does not address the granular rerouting needs for specific NMS traffic or the 10.6.6.6 destination.
