Configuration procedure

1) Configure

addresses and unicast routing

Configure the IP address and subnet mask of each interface as per

Figure 1-6

. The detailed

configuration steps are omitted here.

Configure OSPF for interoperability among the switches. Ensure the network-layer interoperation on

the PIM-SM domain and dynamic update of routing information among the switches through a unicast

routing protocol. The detailed configuration steps are omitted here.

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 Switch D, enable PIM-SM on each interface, and enable IGMPv3 and

IGMP SSM mapping on VLAN-interface 400.
