Network requirements
As shown in Figure 324, 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.
IGMPv2 runs between Firewall A and N1 and between Firewall B/Firewall C and N2. Firewall B serves
as the IGMP querier in N2 because it has a lower IP address.
