Configuration procedure
Configure IP addresses and unicast routing
1.
Configure the IP address and subnet mask for each interface according to
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 (details not shown).
Enable IP multicast routing, and enable PIM-DM and IGMP
2.
# Enable IP multicast routing on Switch B, enable PIM-DM on each interface, and enable IGMP on
VLAN-interface 100.
<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 (details not shown).
# Use the display multicast rpf-info command to view the RPF route to Source on Switch B.
[SwitchB] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: Vlan-interface102, RPF neighbor: 30.1.1.2
Referenced route/mask: 50.1.1.0/24
Referenced route type: igp
Route selection rule: preference-preferred
Load splitting rule: disable
The output shows that the current RPF route on Switch B is contributed by a unicast routing protocol and
the RPF neighbor is Switch A.
