R3303-HP HSR6800 Routers IP Multicast Configuration Guide

[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.

4. 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

5. Verify 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: GigabitEthernet2/0/3, 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

[RouterC] display multicast rpf-info 50.1.1.100

RPF information about source 50.1.1.100:

RPF interface: GigabitEthernet2/0/2, 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. The source for

these RPF routes is the configured static multicast route.

Multicast forwarding over GRE tunnels

Network requirements

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 Receiver can

receive the multicast data from Source.
