To complete OSPF neighbor configuration between R1 and R3 (authentication set and interfaces in the same 192.168.1.0/30), what two steps are next? (Choose two.)

For OSPF neighbors to form an adjacency, their interfaces must be active in OSPF and belong to the same area. Configuring the interfaces as OSPF active (e.g., using the network command or ip ospf <process-id area <area-id on the interface) enables OSPF on those interfaces. Matching area IDs are crucial for OSPF to consider routers as part of the same routing domain segment. While hello and dead timers must match, they are usually default and don't require explicit configuration unless changed. The OSPF process ID is locally significant and doesn't need to match between neighbors. Router IDs must be unique within an OSPF domain, not the same.
