Multicast Forwarding Over A Gre Tunnel - HP MSR1002-4 Configuration Manual

[RouterB] display multicast rpf-info 50.1.1.100
[RouterC] display multicast rpf-info 50.1.1.100
No output is displayed because no RPF routes to Source 2 exist on Router B and Router C.
5. Configure a static multicast route:
# Configure a static multicast route on Router B and specify Router A as its RPF neighbor to
Source 2.
[RouterB] ip rpf-route-static 50.1.1.100 24 30.1.1.2
# Configure a static multicast route on Router C and specify Router B as its RPF neighbor to
Source 2.
[RouterC] ip rpf-route-static 50.1.1.100 24 20.1.1.2
Verifying the configuration
# Display RPF information for Source 2 on Router B.
[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
# Display RPF information for Source 2 on Router C.
[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. These RPF
routes are the configured static multicast routes.

Multicast forwarding over a GRE tunnel

Network requirements
As shown in
•
Multicast routing and PIM-DM are enabled on Router A and Router C. Router B does not
support multicast.
•
Router A, Router B, and Router C run OSPF. The source-side interface GigabitEthernet 1/0/1
on Router A does not run OSPF.
Configure a GRE tunnel so that the receiver host can receive the multicast data from Source.
