Network requirements
As shown in Figure 22:
VOD streams are sent to receiver hosts in multicast.
Receiver hosts of different organizations form stub networks N1 and N2. Host A and Host C are receiver hosts in N1 and N2, respectively.
IGMPv2 runs between Switch A and N1, and between the other two switches and N2.
Switch A acts as the IGMP querier in N1. Switch B acts as the IGMP querier in N2 because it has a lower IP address.
Configure the switches to achieve the following goals:
The hosts in N1 join only multicast group 224.1.1.1.
The hosts in N2 can join any multicast groups.
