11.2.7 Application Example for IGMP

Network Requirements

1. Receivers of different organizations form the stub networks N1 and N2, and Host A and Host
C are the multicast information receivers in N1 and N2 respectively. They receive the
Video-On-Demand information through multicast.
2. In the PIM network, Switch A connects to N1; Switch B and Switch C connect to N2.
3. Switch A connects N1 through its interface VLAN 10, and connects the other devices in the
PIM network through interface VLAN 11.
4. Switch B and Switch C connect to N2 through their interface VLAN 20 respectively. Switch B
connects to the other devices in PIM through interface VLAN 21, and Switch C connects to
the other devices in PIM through interface VLAN 22.
5. IGMPv3 is required between Switch A and N1. IGMPV2 is required among Switch B, Switch C
and N2, with Switch B as the IGMP querier.

Configuration Procedure

1) Configure the interface IP addresses and the unicast routing protocol
Configure the IP address and subnet mask of each interface as the diagram above. The detailed
configuration steps are omitted here.
Configure the switches to access each other through OSPF protocol. Ensure the network-layer
intercommunication among Switch A, Switch B and Switch C. The dynamic routing information is
updated among the three switches via the unicast routing protocol. The detailed configuration
steps are omitted here.
2) Enable the IP multicast routing, and enable the IGMP function on the interfaces of the
user-side.
