Basic IGMP functions configuration example

Network requirements
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 Switch A and N1. IGMPv2 runs between the other two switches and N2. Switch
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.
