IGMP Configuration Examples

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.
Switch A in the PIM network connects to N1, and both Switch B and Switch C connect to N2.
Switch A connects to N1 through VLAN-interface 100, and to other devices in the PIM network
through VLAN-interface 101.
Switch B and Switch C connect to N2 through their respective VLAN-interface 200, and to other
devices in the PIM network through VLAN-interface 201 and VLAN-interface 202 respectively.
IGMPv2 is required between Switch A and N1. IGMPv2 is also required between the other two
switches and N2, Switch B serves as the IGMP querier in N2 because its IP address is lower.

Configuration procedure
1) Configure IP addresses and unicast routing
Configure the IP address and subnet mask of each interface as per
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 switches
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 Switch A, enable PIM-DM on each interface, and enable IGMP on
VLAN-interface 100.
