Refer to the exhibit. Frame Relay connectivity has been configured in the network and OSPF is used as the routing protocol. Router R1 can successfully ping the router R2 serial interface. When R1 attempts to ping network 192.168.3.0/24 the ping fails. What additional configuration should be applied on all routers to remedy the problem?

Add the broadcast keyword in the Frame Relay map command on both routers.

Issue the frame-relay interface-dlci command in addition to the frame-relay map command on both router interfaces.

Remove the frame-relay map command and replace with the frame-relay interface-dlci command on both router interfaces.

Apply the no frame-relay inverse-arp command on both router interfaces.
