[DeviceA] interface gigabitethernet 0/2
[DeviceA-GigabitEthernet0/2] pim dm
[DeviceA-GigabitEthernet0/2] quit
The configuration on Device B is similar to that on Device A. The specific configuration steps are omitted
here.
# Use the display multicast rpf-info command to view the information of the RPF route to Source 2
on Device B and Device C.
[DeviceB] display multicast rpf-info 50.1.1.100
[DeviceC] display multicast rpf-info 50.1.1.100
No information is displayed. This means that no RPF route to Source 2 exists on Device B and Device C.
Step3 Configure a multicast static route
# Configure a multicast static route on Device B, specifying Device A as its RPF neighbor on the route to
Source 2.
[DeviceB] ip rpf-route-static 50.1.1.100 24 30.1.1.2
# Configure a multicast static route on Device C, specifying Device B as its RPF neighbor on the route to
Source 2.
[DeviceC] ip rpf-route-static 50.1.1.100 24 20.1.1.2
Step4 Verify the configuration
# Use the display multicast rpf-info command to view the RPF routes to Source 2 on Device B and
Device C.
[DeviceB] 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: multicast static
Route selection rule: preference-preferred
Load splitting rule: disable
[DeviceC] 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
As shown above, the RPF routes to Source 2 exist on Device B and Device C. The source for these RPF
routes is the configured multicast static route.
Multicast Forwarding over GRE Tunnels
Network requirements
• Multicast routing and PIM-DM are enabled on Device A and Device C. Device B does not support
multicast.
• OSPF is running on Device A, Device B, and Device C.
• Configure a GRE tunnel so that Receiver can receive the multicast data from Source.
