IGMP Configuration Examples
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.
• Device A in the PIM network connects to N1, and both Device A and Device C connect to another
stub network, N2.
