III. Configuration procedure
1) Configure the interface IP addresses and unicast routing protocol for each switch
Configure the IP address and subnet mask for each interface as per
Figure 7-4. The
detailed configuration steps are omitted here.
Enable OSPF on Switch B and Switch C. Ensure the network-layer interoperation
among Switch B and Switch C. Ensure that the switches can dynamically update their
routing information by leveraging the unicast routing protocol. The specific
configuration steps are omitted here.
2) Enable IP multicast routing, and enable PIM-DM and IGMP
# Enable IP multicast routing on Switch C, enable PIM-DM on each interface, and
enable IGMP on the host-side interface VLAN-interface 100.
