Generate unicast traffic

Generate multicast traffic
- UE1: ping -I oip0 224.0.0.3
- UE1: ping -I oip0 224.0.0.3 #flow 3
- UE1: ping -I oip0 224.0.0.5 #flow 4
Expected results:
- UE2 can receive both unicast and multicast traffic
- UE3 can only receive multicast traffic
- UE2 can receive both unicast and multicast traffic (flow 1, flow 3 and flow 4)
- UE3 can receive both unicast and multicast traffic (flow 2, flow 3 and flow 4)
Note:
- Use wireshark to observe unicast/multicast traffic from UE2 and multicast traffic from UE3.
- Use wireshark to observe unicast/multicast traffic from UE2/3.
