IGMP Configuration Examples
Basic IGMP Functions Configuration Example
Network requirements
z 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.
z Switch A in the PIM network connects to N1, and both Switch B and Switch C connect to
N2.
z Switch A connects to N1 through VLAN-interface 100, and to other devices in the PIM
network through VLAN-interface 101.
z 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.
z IGMPv2 is required between Switch A and N1. IGMPv2 is also required between the other
two switches and N2. Switch B acts as the IGMP querier in N2 because it has a lower IP
address.
