The configuration on Firewall 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
Firewall B and Firewall C.
[FirewallB] display multicast rpf-info 50.1.1.100
[FirewallC] display multicast rpf-info 50.1.1.100
No information is displayed. This means that no RPF route to Source 2 exists on Firewall B and Firewall
C.
3. Configure a multicast static route
# Configure a multicast static route on Firewall B, specifying Device A as its RPF neighbor on the route to
Source 2.
[FirewallB] ip rpf-route-static 50.1.1.100 24 30.1.1.2
# Configure a multicast static route on Firewall C, specifying Firewall B as its RPF neighbor on the route
to Source 2.
[FirewallC] 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 Firewall B and
Firewall C.
[FirewallB] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: GigabitEthernet 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
[FirewallC] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: GigabitEthernet 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
As shown above, the RPF routes to Source 2 exist on Firewall B and Firewall C. The source for these RPF
routes is the configured multicast static route.
Example for multicast forwarding over GRE tunnels
Network requirements
• Multicast routing and PIM-DM are enabled on Firewall A and Firewall C. Device B does not support
multicast.
• OSPF is running on Firewall A, Device B, and Firewall C.
• Configure a GRE tunnel so that Receiver can receive the multicast data from Source.
