Multicast Forwarding Over A Gre Tunnel - HP 5920 series Configuration Manual

[SwitchB] display multicast rpf-info 50.1.1.100
[SwitchC] display multicast rpf-info 50.1.1.100
No output is displayed. It indicates that that no RPF routes to the source 2 exist on Switch B or
Switch C.
Configure a static multicast route:
4.
# Configure a static multicast route on Switch B, specifying Switch A as its RPF neighbor on the
route to the source 2.
[SwitchB] ip rpf-route-static 50.1.1.100 24 30.1.1.2
# Configure a static multicast route on Switch C, specifying Switch B as its RPF neighbor on the
route to the source 2.
[SwitchC] ip rpf-route-static 10.1.1.100 24 20.1.1.2
Verifying the configuration
Use the display multicast rpf-info command on Switch B and Switch C to display information about their
RPF routes to the source 2.
[SwitchB] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: Vlan-interface102, 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
[SwitchC] display multicast rpf-info 50.1.1.100
RPF information about source 50.1.1.100:
RPF interface: Vlan-interface101, 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 the source 2 exist on Switch B and Switch C. The routes are the
configured static routes.

Multicast forwarding over a GRE tunnel

Network requirements
Multicast routing and PIM-DM are enabled on Switch A and Switch C. Switch B does not support
multicast. OSPF is running on Switch A, Switch B, and Switch C.
Perform the configuration so that the receiver host can receive the multicast data from the source.
