The configuration on Router B is similar to that on Router A. The specific configuration steps are omitted
here.
# Use display multicast rpf-info to view the information of the RPF route to Source 2 on Router B and
Router C.
[RouterB] display multicast rpf-info 50.1.1.100
[RouterC] display multicast rpf-info 50.1.1.100
No information is displayed. This means that no RPF route to Source 2 exists on Router B and Router C.
Configure a multicast static route
3.
# Configure a multicast static route on Router B, specifying Router A as its RPF neighbor on the route to
Source 2.
[RouterB] ip rpf-route-static 50.1.1.100 24 30.1.1.2
# Configure a multicast static route on Router C, specifying Router B as its RPF neighbor on the route to
Source 2.
[RouterC] ip rpf-route-static 50.1.1.100 24 20.1.1.2
Verify the configuration
4.
# Use display multicast rpf-info to view the RPF routes to Source 2 on Router B and Router C.
[RouterB] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: GigabitEthernet1/0/3, RPF neighbor: 30.1.1.2
Referenced route/mask: 50.1.1.0/24
Referenced route type: multicast static
Route selection rule: preference-preferred
Load splitting rule: disable
[RouterC] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: GigabitEthernet1/0/2, 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 routes to Source 2 exist on Router B and Router C. The source for these RPF
routes is the configured multicast static route.

Multicast forwarding over a GRE tunnel

Network requirements
Multicast routing and PIM-DM are enabled on Router A and Router C. Router B does not support
multicast.
OSPF is running on Router A, Router B, and Router C.
Configure a GRE tunnel so that Receiver can receive the multicast data from Source.
