Multicast Forwarding Over A Gre Tunnel - HPE FlexNetwork 5510 HI 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 because no RPF routes to Source 2 exist on Switch B or Switch C.
Configure a static multicast route:
5.
# Configure a static multicast route on Switch B and specify Switch A as its RPF neighbor on the
route to Source 2.
[SwitchB] ip rpf-route-static 50.1.1.100 24 30.1.1.2
# Configure a static multicast route on Switch C and specify Switch B as its RPF neighbor on
the route to Source 2.
[SwitchC] ip rpf-route-static 10.1.1.100 24 20.1.1.2
Verifying the configuration
# Display RPF information for Source 2 on Switch B.
[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
# Display RPF information for Source 2 on Switch C.
[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 Source 2 exist on Switch B and Switch C. The routes are
the configured static routes.

Multicast forwarding over a GRE tunnel

Network requirements
As shown in
• Multicast routing and PIM-DM are enabled on Switch A and Switch C.
• Switch B does not support multicast.
• Switch A, Switch B, and Switch C run OSPF.
Configure the switches so that the receiver host can receive the multicast data from Source.
