11 IP Addressing Address Mask Unicast IP End Host addressing Multicast IP Group addressing Multicast address = flow address Network Host Multicast Group Address Range

12 Multicast Conceptual Model Source First-hop router Source segment Multicast data flow PIM Last-hop router IGMP Receiver segment TECSPV

13 13 IP Routing Protocols src addr: A unique packet addressed to each destination. OSPF Unicast Routing OSPF ISIS BGP

14 14 IP Routing Protocols src addr: A unique packet addressed to each destination. OSPF Unicast Routing OSPF ISIS BGP src addr: replicated at each node along the tree. PIM PIM PIM IGMP IGMP IGMP Multicast Routing PIM IGMP

15 IGMPv2 Joining a Group Receiver 2 Eth0: I want to receive group Receiver 1 Eth0: Multicast Stream Note: The IGMP message does not include the identity of the multicast source IGMP Membership Report Requested Group: Source IP: Dest IP: Non-receiver First-hop router Eth0: TECSPV

16 IGMPv3 Joining a Group I want from source IP Receiver 1 Eth0: Receiver 2 Eth0: I also want from source IP IGMP Membership Report Requested Group: Group Source: Source IP: Destination IP: First-hop router receives ALL IGMPv3 reports (no report suppression) Source Non-receiver TECSPV
