Configuration procedure
1. Configure IP addresses and unicast routing
Configure the IP address and subnet mask for each interface as per Figure 31 . (details not shown)
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. (details not shown)
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
VLAN-interface 100.
<SwitchC> system-view
[SwitchC] multicast routing-enable
[SwitchC] interface vlan-interface 100
[SwitchC-Vlan-interface100] igmp enable
[SwitchC-Vlan-interface100] pim dm
[SwitchC-Vlan-interface100] quit
[SwitchC] interface vlan-interface 101
[SwitchC-Vlan-interface101] pim dm
[SwitchC-Vlan-interface101] quit
# Enable IP multicast routing on Switch A and enable PIM-DM on each interface.
<SwitchA> system-view
[SwitchA] multicast routing-enable
[SwitchA] interface vlan-interface 300
[SwitchA-Vlan-interface300] pim dm
[SwitchA-Vlan-interface300] quit
[SwitchA] interface vlan-interface 102
[SwitchA-Vlan-interface102] pim dm
[SwitchA-Vlan-interface102] quit
The configuration on Switch B is similar to that on Switch A. (details not shown)
