Configuration procedure

1. Assign an IP address and subnet mask for each interface according to Figure 19. (Details not

shown.)

2. Enable OSPF on Switch B and Switch C to make sure the following conditions are met: (Details not

shown.)

{ The switches are interoperable at the network layer.

{ The switches can dynamically update their routing information.

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

# On Switch C, enable IP multicast routing.

<SwitchC> system-view

[SwitchC] multicast routing

[SwitchC-mrib] quit

# Enable IGMP on VLAN-interface 100 (the interface that connects to the receiver host).

[SwitchC] interface vlan-interface 100

[SwitchC-Vlan-interface100] igmp enable

[SwitchC-Vlan-interface100] quit

# Enable PIM-DM on VLAN-interface 101.

[SwitchC] interface vlan-interface 101

[SwitchC-Vlan-interface101] pim dm

[SwitchC-Vlan-interface101] quit

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

<SwitchA> system-view

[SwitchA] multicast routing

[SwitchA-mrib] quit

[SwitchA] interface vlan-interface 300

[SwitchA-Vlan-interface300] pim dm

[SwitchA-Vlan-interface300] quit
