Multicast Forwarding Over Gre Tunnels - HP MSR ASM Configuration Manual

[RouterB] display multicast rpf-info 50.1.1.100
[RouterC] display multicast rpf-info 50.1.1.100
No information is displayed. It means that that no RPF route to Source 2 exists on Router B and
Router C.
3. Configure a static multicast route:
# Configure a static multicast 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 static multicast 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
Verifying the configuration
# Display information about 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: Ethernet1/3, 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: Ethernet1/2, 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 static multicast route.

Multicast forwarding over GRE tunnels

Network requirements
As shown in
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.
Figure 42, multicast routing and PIM-DM are enabled on Router A and Router C. Router B
