![]() igmp-snooping static-router-port vlan 100 # Configure GigabitEthernet 1/0/3 as a static router port. port gigabitethernet 1/0/1 to gigabitethernet 1/0/3 # Create VLAN 100, and assign GigabitEthernet 1/0/1 through GigabitEthernet 1/0/3 to the VLAN. # Enable PIM-DM on GigabitEthernet 1/0/2. Then, multicast data can flow to the receivers nearly uninterruptedly along the path of Switch A-Switch C when the path of Switch A-Switch B-Switch C is blocked.Īssign an IP address and subnet mask to each interface, as shown in Figure 13 For more information about the STP, see Layer 2-LAN Switching Configuration Guide.Ĭonfigure GigabitEthernet 1/0/3 on Switch A as a static router port. In this case, the multicast delivery is interrupted during the process. When this path is blocked, a minimum of one IGMP query-response cycle must be completed before multicast data flows to the receivers along the path of Switch A-Switch C. ![]() Multicast data flows to the receivers attached to Switch C only along the path of Switch A-Switch B-Switch C. To avoid data loops, the forwarding path from Switch A to Switch C is blocked. To enhance the reliability of multicast traffic transmission, configure GigabitEthernet 1/0/3 and GigabitEthernet 1/0/5 on Switch C as static member ports for multicast group 224.1.1.1. Host A and host C are permanent receivers of multicast group 224.1.1.1.Ĭonfigure static ports to meet the following requirements: ![]() Switch A, Switch B, and Switch C run IGMPv2 snooping. Router A runs IGMPv2 and acts as the IGMP querier.
