Basic IGMP functions configuration example
Network requirements
• 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.
• Firewall A in the PIM network connects to N1, and both Firewall B and Firewall C connect to another
stub network, N2.
• Firewall A connects to N1 through GigabitEthernet 0/1, and to other devices in the PIM network
through GigabitEthernet 0/0.
• Firewall B and Firewall 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 Firewall A and N1. IGMPv2 is also required between the other two
firewalls and N2. Firewall B acts as the IGMP querier in N2 because it has a lower IP address.

Configuration procedure
1. Configure IP addresses and unicast routing
Configure the IP address and subnet mask of each interface as per Figure 209. T
he 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 firewalls
through a unicast routing protocol. The detailed configuration steps are omitted here.
2. Enable IP multicast routing, and enable PIM-DM and IGMP
# Enable IP multicast routing on Firewall A, enable PIM-DM on each interface, and enable IGMP on
GigabitEthernet 0/1.
