CAUTION:
The reset igmp group command might cause an interruption of receivers’ reception of multicast data.
IGMP configuration examples at the CLI
This section provides examples of configuring IGMP on firewalls.
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 SecPath A and N1 and between the other two routers and N2. SecPath 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.

Configuration procedure
1. Configure IP addresses and unicast routing:
Configure the IP address and subnet mask of each interface as per
Figure 328 . (Details not
shown.)
Enable OSPF on firewalls on the PIM network to make sure the network-layer on the PIM network
is interoperable and the routing information among the firewalls can be dynamically updated.
(Details not shown.)
2. Enable IP multicast routing, and enable PIM-DM and IGMP:
