IGMP Configuration Example
Network requirements
• As shown in Figure 7 , receivers receive VOD information through multicast. Receivers of different
organizations form stub networks N1 and N2, and Host A and Host C are receivers in N1 and N2
respectively.
• Device A in the PIM network connects to N1, and both Device B and Device C connect to another
stub network, N2.
• Device A connects to N1 through GigabitEthernet 0/1, and to other devices in the PIM network
through GigabitEthernet 0/0.
• Device B and Device C connect to N2 through their respective GigabitEthernet 0/1, and to other
devices in the PIM domain through their respective GigabitEthernet 0/0.
• IGMPv2 is required between Device A and N1. IGMPv2 is also required between Device B/Device
C and N2. Device B serves as the IGMP querier in N2 because it has a lower IP address.

Configuration procedure
Step1 Configure IP addresses and unicast routing
Configure the IP address of each interface and the security zone as per Figure 7 . The detailed
configuration steps are omitted here.
Configure the OSPF protocol for interoperation on the PIM network. Ensure the network-layer
interoperation on the PIM network and dynamic update of routing information among the devices
through a unicast routing protocol. The detailed configuration steps are omitted here.
Step2 8Enable IP multicast routing, and enable PIM-DM and IGMP
# On Device A, enable IP multicast routing, enable PIM-DM on each interface, and enable IGMP on
GigabitEthernet 0/1.
