Configuration procedure
Step1 Configure IP addresses and unicast routing
Configure the IP address and subnet mask for each interface as per Figure 5 . The detailed configuration
steps are omitted here.
Enable OSPF on the devices in the PIM-DM domain. Ensure the network-layer interoperation among the
devices in the PIM-DM domain. Ensure that the devices can dynamically update their routing information
by leveraging the unicast routing protocol. The specific configuration steps are omitted here.
Step2 Enable IP multicast routing, and enable PIM-DM and IGMP
# Enable IP multicast routing on Device B, enable PIM-DM on each interface, and enable IGMP on
GigabitEthernet 0/1.
