5.6 IGMP Configuration Example
I. Network requirements
z
Receivers receive VOD information through the multicast mode. 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
IGMPv3 is required between Switch A and N1. IGMPv2 is required between the
other two switches and N2, with Switch B as the IGMP querier.
