The network might be, e.g., the Internet, or the private network offered by a service provider such as AT&T. A node represents a physical device, such as a switch or router, connected to other devices. The term switch is typically used to refer to a device performing layer 2 data ...
is, the network segment where a Layer 3 network device is connected to user hosts). Hosts use IGMP to join or leave multicast groups, and upstream Layer 3 multicast devices use IGMP to manage and maintain group memberships. IGMPcanexchange information with upper-layer multicast routing protocols...
Multicast Routing:When the cable provider generates data (e.g., streaming an on-demand event), it sends out a single copy of the data packet with the multicast destination IP address. Routers in the network, using multicast routing protocols like PIM, determine the best paths to forward these...

IGMP (Internet Group Management Protocol) and PIM (Protocol Independent Multicasting) are the two protocols provide support for IPv4 multicasting. Multicast can be defined as "send once and receive many" type of network communication. Multicast type of network communication consumes less network bandwidt...
Routers use multicast routing protocols for forwarding multicast data.The following figure illustrates a multicast-enabled intranet.In this illustration, the hosts and routers are multicast-enabled so that the following can occur:The sending host sends multicast datagrams to a designated group address. ...
As shown in Figure 1-6, to allow users A, B, and C to receive data traffic from the source if the multicast transmission mode is used, perform the following configurations: Configure unicast IP addresses for interconnected interfaces on the network. Configure unicast routing protocols on the en...
message. Using the routing information available with the help of the different communication protocols, protocol-independent multicast can function without being dependent on any specific routing protocol. In other words, protocol-independent multicast does not use its own mechanism of topology discovery....
Layer-management protocols that belong to the network layer are: Routing protocols Multicast group management Network-layer address assignment. The Network Interface Layer Network Interface Layer is this layer of the four-layer TCP/IP model. This layer is also called a network access layer. It help...
routes are decided based on the IP destination and hop count. RIPv2 advanced this method and started to include subnet masks and gateways. Furthermore, the routing table in RIPv1 is broadcast to every station on the attached network whereas RIPv2 sends the routing table to a Multicast address ...
