Configuration procedure

1. Assign IP addresses and configure unicast routing:

a. Assign an IP address and subnet mask to each interface according to Figure 16. (Details not

shown.)

b. Configure OSPF on the routers in the PIM-SM domain to make sure they are interoperable at

the network layer and they can dynamically update their routing information. (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:

# Enable IP multicast routing on Router D, enable PIM-SM on each interface and enable IGMPv3

and IGMP SSM mapping on Ethernet 1/1.
