4000 Router Series IP Multicast Configuration Guide

2. Enable OSPF on Router B and Router C to make sure the network-layer on the PIM-DM network is

interoperable and the routing information among the routers can be dynamically updated. (Details

not shown.)

3. Enable IP multicast routing, and enable IGMP and PIM-DM:

# On Router C, enable IP multicast routing globally, enable IGMP on Ethernet 1/1, and enable

PIM-DM on each interface.

<RouterC> system-view

[RouterC] multicast routing

[RouterC-mrib] quit

[RouterC] interface ethernet 1/1

[RouterC-Ethernet1/1] igmp enable

[RouterC-Ethernet1/1] pim dm

[RouterC-Ethernet1/1] quit

[RouterC] interface ethernet 1/2

[RouterC-Ethernet1/2] pim dm

[RouterC-Ethernet1/2] quit

# On Router A, enable IP multicast routing globally and enable PIM-DM on each interface.

<RouterA> system-view

[RouterA] multicast routing

[RouterA-mrib] quit

[RouterA] interface ethernet 1/1

[RouterA-Ethernet1/1] pim dm

[RouterA-Ethernet1/1] quit

[RouterA] interface ethernet 1/2

[RouterA-Ethernet1/2] pim dm

[RouterA-Ethernet1/2] quit

# Enable IP multicast routing and PIM-DM on Router B in the same way Router A is configured.

(Details not shown.)

# Use the display multicast rpf-info command on Router B and Router C to display information

about their RPF routes to the source 2.

[RouterB] display multicast rpf-info 50.1.1.100

[RouterC] display multicast rpf-info 50.1.1.100

No output is displayed, so no RPF routes to the source 2 exist 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 the 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 the source 2.

[RouterC] ip rpf-route-static 50.1.1.100 24 20.1.1.2

Verifying the configuration

Use the display multicast rpf-info command on Router B and Router C to display information about their

RPF routes to the source 2.

[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
