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
[SwitchC] interface vlan-interface 300
[SwitchC-Vlan-interface300] pim dm
[SwitchC-Vlan-interface300] quit
[SwitchC] interface vlan-interface 102
[SwitchC-Vlan-interface102] pim dm
[SwitchC-Vlan-interface102] quit
The configuration on Switch B is similar to that on Switch A (details not shown).
# Use the display multicast rpf-info command to view 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
No information is displayed. It indicates that no RPF route to Source 2 exists on Switch B or Switch C.
3. Configure a multicast static route
# Configure a multicast static route on Switch B, specifying Switch A as its RPF neighbor on the route to
Source 2.
[SwitchB] ip rpf-route-static 50.1.1.100 24 30.1.1.2
# Configure a multicast static route on Switch C, specifying Switch B as its RPF neighbor on the route to
Source 2.
[SwitchC] ip rpf-route-static 10.1.1.100 24 20.1.1.2
4. Verify the configuration
# Use the display multicast rpf-info command to view the RPF routes to Source 2 on Switch B and Switch
C.
[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: multicast static
