Configuration procedure
1. Configure the IP address and subnet mask for each interface as per Figure 27. (Details not shown.)
2. Enable OSPF on Switch B and Switch C to make sure they are interoperable at the network layer
and they can dynamically update their routing information. (Details not shown.)
3. 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
# Enable IP multicast routing and PIM-DM on Switch B in the same way. (Details not shown.)
# Use the display multicast rpf-info command to display the RPF routes to Source 2 on Switch B
and Switch C.
[SwitchB] display multicast rpf-info 50.1.1.100
[SwitchC] display multicast rpf-info 50.1.1.100
