group entries of a specified IGMP
group or all IGMP groups.

IGMP configuration examples

This section provides examples of configuring IGMP on routers.

Basic IGMP functions configuration example

Network requirements
As shown in
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.
Figure 15, the receivers receive VOD information through multicast. The receivers of different
