Querier for IGMP: 10.110.2.1 (this Firewall)
Total 1 IGMP Group reported
SSM mapping configuration example
Network requirements
The PIM-SM domain applies both the ASM model and SSM model for multicast delivery. Firewall D's
GigabitEthernet 0/3 serves as the C-BSR and C-RP. The SSM group range is 232.1.1.0/24.
IGMPv3 runs on Firewall D's GigabitEthernet 0/1. The Receiver host runs IGMPv2, and does not support
IGMPv3. Therefore, the Receiver host cannot specify expected multicast sources in its membership
reports.
Source 1, Source 2, and Source 3 send multicast packets to multicast groups in the SSM group range.
You can configure the IGMP SSM mapping feature on Firewall D so that the receiver host will receive
multicast data from Source 1 and Source 3 only.

Configuration procedure
1. Configure IP addresses and unicast routing:
Configure the IP address and subnet mask of each interface as per Figure 330. (Details not
shown.)
Enable OSPF on firewalls on
the PIM-SM network to make sure the network-layer on the PIM-SM
network is interoperable and the routing information among the firewalls can be dynamically
updated. (Details not shown.)
2. Enable IP multicast routing, enable PIM-SM on each interface, and enable IGMP and IGMP SSM
mapping on the host-side interface:
