Network requirements
PIM-DM runs in the network. All routers in the network support multicast.
Firewall A, Firewall B and Firewall C run OSPF.
Typically, Receiver can receive the multicast data from Source through the path Firewall A – Firewall B,
which is the same as the unicast route.
Perform the following configuration so that Receiver can receive the multicast data from Source through
the path Firewall A – Firewall C – Firewall B, which is different from the unicast route.

Configuration procedure
1. Configure IP addresses and unicast routing:
Configure the IP address and subnet mask for each interface as per Figure 317. (Details not
shown.)
Enable OSPF on the firewall
s in the PIM-DM domain to make sure the network-layer on the PIM-DM
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:
# Enable IP multicast routing on Firewall B, enable PIM-DM on each interface, and enable IGMP
on GigabitEthernet 0/1.
