Configuration procedure

1. Assign the IP address and subnet mask to each interface as shown in Figure 23. (Details not

shown.)

2. Configure OSPF on the PIM network to make sure the network-layer is interoperable on the PIM

network and the routing information among the switches can be dynamically updated. (Details not

shown.)

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

# On Switch A, enable IP multicast routing globally, enable IGMP on VLAN-interface 100, and

enable PIM-DM on each interface.

<SwitchA> system-view

[SwitchA] multicast routing-enable

[SwitchA] interface vlan-interface 100

[SwitchA-Vlan-interface100] igmp enable

[SwitchA-Vlan-interface100] pim dm

[SwitchA-Vlan-interface100] quit

[SwitchA] interface vlan-interface 101

[SwitchA-Vlan-interface101] pim dm

[SwitchA-Vlan-interface101] quit

# On Switch B, enable IP multicast routing globally, enable IGMP on VLAN-interface 200, and

enable PIM-DM on each interface.
