H3C S7500E Series Ethernet Switches
III. Configuration procedure
1) Configure the interface IP addresses and enable unicast routing on each switch
Configure the IP address and subnet mask for each interface as per
detailed configuration steps are omitted here.
Enable OSPF on the switches in the PIM-DM domain. Ensure the network-layer
interoperation among the switches in the PIM-DM domain. 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 B, enable PIM-DM on each interface, and
enable IGMP on the host-side interface Ethernet 1/0.
<SwitchB> system-view
[SwitchB] multicast routing-enable
[SwitchB] interface vlan-interface 100
[SwitchB-Vlan-interface100] igmp enable
[SwitchB-Vlan-interface100] pim dm
[SwitchB-Vlan-interface100] quit
[SwitchB] interface vlan-interface 101
[SwitchB-Vlan-interface101] pim dm
[SwitchB-Vlan-interface101] quit
[SwitchB] interface vlan-interface 102
[SwitchB-Vlan-interface102] pim dm
[SwitchB-Vlan-interface102] 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 200
[SwitchA-Vlan-interface200] pim dm
[SwitchA-Vlan-interface200] quit
[SwitchA] interface vlan-interface 102
[SwitchA-Vlan-interface102] pim dm
[SwitchA-Vlan-interface102] quit
[SwitchA] interface vlan-interface 103
[SwitchA-Vlan-interface103] pim dm
[SwitchA-Vlan-interface103] quit
The configuration on Switch C is similar to the configuration on Switch A. The specific
configuration steps are omitted here.
# Use the display multicast rpf-info command to view the RPF route to Source on
Switch B.
