Refer to the exhibit. Two Cisco Nexus 9000 Series Switches exchange OSPF routing information with R1. Which action accomplishes this goal?
The correct answer is C. Add layer3 peer-router under VPC domain. Configuring layer3 peer-router at the vPC-domain level makes the two Nexus switches present themselves as a single OSPF neighbor to R1. This setting synchronizes ARP/adjacency state across the peer pair and allows a routed vPC EtherChannel (Po10) to form a proper OSPF adjacency…

Explanation
Configuring layer3 peer-router at the vPC-domain level makes the two Nexus switches present themselves as a single OSPF neighbor to R1. This setting synchronizes ARP/adjacency state across the peer pair and allows a routed vPC EtherChannel (Po10) to form a proper OSPF adjacency without split‑brain issues.
