Network requirements

The receivers receive VOD information through multicast. The receivers of different organizations form

stub networks N1 and N2. Host A and Host C are receivers in N1 and N2, respectively.

Router A in the PIM network connects to N1, and both Router B and Router C connect to another stub

network, N2.

IGMPv2 runs between Router A and N1, and between the other two routers and N2. Router B acts as the

IGMP querier in N2 because it has a lower IP address.

The hosts in N1 can join only multicast group 224.1.1.1, and the hosts in N2 can join any multicast

groups.
