3Com S7906E Configuration Manual page 986

Configure the IP address and subnet mask for each interface as per
configuration steps are omitted here.
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. The specific configuration steps are omitted here.
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 the
host-side interface 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. The specific configuration steps are omitted
here.
# 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. This means that no RPF route to Source 2 exists on Switch B and 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 50.1.1.100 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.
