Configuration procedure
1. Configure the IP address and subnet mask for each interface as per Figure 63. (Details not shown.)
2. Configure OSPF on the switches in each AS to make sure the switches in each AS are
interoperable at the network-layer, and they can dynamically update their routing information.
(Details not shown.)
3. Enable IP multicast routing, enable PIM-SM and IGMP, and configure a PIM-SM domain border:
# Enable IP multicast routing on Switch C, enable PIM-SM on each interface, and enable IGMP on
the host-side interface VLAN-interface 200.
