Source 1, Source 2, and Source 3 send IPv6 multicast packets to multicast groups in the IPv6 SSM group
range. You can configure the MLD SSM mapping feature on Firewall so that the receiver host will receive
IPv6 multicast data from Source 1 and Source 3 only.

Configuration procedure
1. Enable IPv6 forwarding and configure IPv6 addresses and IPv6 unicast routing.
Enable IPv6 forwarding on routers and the firewall, and configure an IPv6 address and prefix
length for each interface as shown in Figure 6. (Details not shown.)
Configure OSPF on the routers and the firewall to make sure the network-layer in the IPv6 PIM-SM
domain is interoperable and routing information among the routers and the firewall can be
dynamically updated. (Details not shown.)
2. Enable IPv6 multicast routing, enable IPv6 PIM-SM on each interface and enable MLD and MLD
SSM mapping on the host-side interface:
# Enable IPv6 multicast routing on Firewall, enable IPv6 PIM-SM on each interface and enable
MLD (version 2) and MLD SSM mapping on GigabitEthernet 0/1.
