# On Router A, enable IP multicast routing globally, and enable PIM-DM on each interface.
<RouterA> system-view
[RouterA] multicast routing-enable
[RouterA] interface ethernet 1/1

# Enable IP multicast routing and PIM-DM on Router B in the same way. (Details not shown.)
# Use the display multicast rpf-info command to display the RPF route to the source on the
firewall.
[Firewall] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: GigabitEthernet0/3, 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 the firewall is contributed by a unicast routing
protocol and the RPF neighbor is Router A.
d. Configure a static multicast route on the firewall, specifying Router C as its RPF neighbor to the
source.
[Firewall] ip rpf-route-static 50.1.1.100 24 20.1.1.2
e. Verifying the configuration
# Display information about the RPF route to the source on the firewall.
[Firewall] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: GigabitEthernet0/2, RPF neighbor: 20.1.1.2
Referenced route/mask: 50.1.1.0/24
Referenced route type: multicast static
Route selection rule: preference-preferred
Load splitting rule: disable
The output shows that the RPF route on the firewall has changed. It is now the configured static
multicast route, and the RPF neighbor is now Router B.
Creating an RPF route
1. Network requirements
PIM-DM runs in the network and all devices in the network support IP multicast. Router B and the
firewall run OSPF, and have no unicast routes to Router A. Typically, the receiver can receive the
multicast data from the source 1 in the OSPF domain.
Perform the following configuration so that the receiver can receive multicast data from Source 2,
which is outside the OSPF domain.
