OSPF router R2 has both point-to-point and broadcast interfaces and it is not a DR for any interfaces. Router R2 detects the link failure between itself and router R1.

Router R2 sends an update to 224.0.0.5 on its broadcast and point-to-point interfaces. The DR does not send any updates.

B.

Router R2 sends an update to 244.0.0.5 on its point-to-point interfaces. The DR sends an update to 224.0.0.6 on the broadcast network.

C.

Router R2 sends an update to 224.0.0.5 out its point-to-point interfaces and an update to 224.0.0.6 out its broadcast interface. The DR sends updates to 224.0.0.5 on the broadcast network.

D.

Router R2 sends an update to 224.0.0.6 out its point-to-point interfaces and an update to 224.0.0.5 out its broadcast interface. The DR sends an update to 224.0.0.6 on the broadcast networks.

An LSP path is configured as follows:
