Multicast Forwarding Over A Gre Tunnel - HP MSR2003 Configuration Manual

[RouterA-GigabitEthernet2/1/1] quit
[RouterA] interface gigabitethernet 2/1/2

[RouterA-GigabitEthernet2/1/2] quit
# Enable IP multicast routing and PIM-DM on Router B in the same way Router A is configured.
(Details not shown.)
4. Display information about their RPF routes 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 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, specifying 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, specifying 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 information about their 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: GigabitEthernet2/1/3, 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: GigabitEthernet2/1/2, 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.
OSPF is running on Router A, Router B, and Router C.
•
Configure a GRE tunnel so that the receiver host can receive the multicast data from Source.
