3 Configure Receiver.

Receiver establishes HTTP connections to the multicast source and sends the list of 
the names of the services provided by the multicast source to the clients (Each 
service has its own multicast address, which is the multicast group). When a 
service is selected, the client sends IGMP packets to join the multicast group, 
through which the receiver can receive the corresponding multicast packets.

After the above configuration, execute display command in any view to display 
the running of IGMP configuration, and to verify the effect of the configuration.

Execute debugging command in corresponding views for the debugging of IGMP.
