R3303-HP HSR6800 Routers IP Multicast Configuration Guide

Figure 23 Network diagram

Configuration procedure

1. Assign an IP address and subnet mask to each interface according to Figure 23. (Details not

shown.)

2. Enable OSPF on Router B and Router C to make sure they are interoperable at the network layer

and they can dynamically update their routing information. (Details not shown.)

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

# Enable IP multicast routing on Router C, enable PIM-DM on each interface, and enable IGMP on

GigabitEthernet 2/0/1.

<RouterC> system-view

[RouterC] multicast routing-enable

[RouterC] interface gigabitethernet 2/0/1

[RouterC-GigabitEthernet2/0/1] igmp enable

[RouterC-GigabitEthernet2/0/1] pim dm

[RouterC-GigabitEthernet2/0/1] quit

[RouterC] interface gigabitethernet 2/0/2

[RouterC-GigabitEthernet2/0/2] pim dm

[RouterC-GigabitEthernet2/0/2] quit

# Enable IP multicast routing on Router A and enable PIM-DM on each interface.

<RouterA> system-view

[RouterA] multicast routing-enable

[RouterA] interface gigabitethernet 2/0/1

[RouterA-GigabitEthernet2/0/1] pim dm

[RouterA-GigabitEthernet2/0/1] quit

[RouterA] interface gigabitethernet 2/0/2

[RouterA-GigabitEthernet2/0/2] pim dm

[RouterA-GigabitEthernet2/0/2] quit

# Configure Router B in the same way as you configure Router A. (Details not shown.)

# Use the display multicast rpf-info command to view the information of the RPF route to Source 2

on Router B and Router C.

[RouterB] display multicast rpf-info 50.1.1.100
