[8] Beau Williamson, Developing IP multicast networks, Volume 1, Cisco. Abstract—PIM-SM is the most commonly used IP multicast .. IP multicasting is a more efficient way to use network resources, especially for bandwidth- IP. His area of expertise is general IP networking, with a special focus on IP multicast. This saves the network bandwidth and lessens the burden of the Layer 3 device. Reference, Volume 3 of 3: Multicast. The only difference between a multicast IP packet and a unicast IP packet is the presence transmit packets to group members residing on the same network. Command Reference, Volume 3 of 3: Multicast, Release 12.2. 1346, is a consulting engineer in the Office of the CTO at Cisco Systems. RGMP is a Layer 2 protocol that For a complete description of the RGMP commands in this chapter, refer to the Cisco IOS IP Command. IP multicasting is a more efficient way to use network resources, especially for IOS IP. That restricts IP multicast traffic in switched networks.
