OSPF is configured over a Frame Relay network as shown in the exhibit. All PVCs are
active. However, R1 and R3 fail to see all OSPF routes in their routing tables. The show ip
ospf neighbor command executed on R2 shows the state of the neighbors. What should be
done to fix the problem?

A.
The ip ospf network broadcast command should be configured on each Frame Relay
interface.

B.
The ip ospf network non-broadcast command should be configured on each Frame Relay
interface.

C.
The ip ospf priority value on the spoke routers should be set to 0.

D.
The ip ospf priority value on the hub router should be set to 0.

E.
The neighbor command should be configured under the OSPF routing process on all
routers.
