Disadvantages of Multicast:
- Lack of congestion control results in increased network degradation as the volume of network traffic rises
- Best effort delivery - can lead to packet drops affecting VOIP/Video delivery
- Eavesdropping is a security issue due to the nature to the protocol
- 224.0.1.1 = NTP protocol
- GLOP and Limited scope addresses are types of Multicast address
- RP-Announce msgs sent to 224.0.1.39
- RP-Discovery msgs (group-to-RP mapping msgs) sent to 224.0.1.40
