Configuration procedure
1. Configure the IP address and subnet mask for each interface as per Figure 56. (Details not shown.)
2. Configure OSPF on the switches to make sure the switches are interoperable at the network-layer,
and they can dynamically update their routing information. (Details not shown.)
3. Enable IP multicast routing, IGMP and PIM-SM:
# Enable IP multicast routing on Switch B, enable IGMP on the host-side interface VLAN-interface
100, and enable PIM-SM on each interface.
