Configuration procedure
1. Assign an IP address and subnet mask to each interface according to Figure 26. (Details not
shown.)
2. Configure OSPF on the switches in the PIM-DM domain to meet the following requirements:
(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 B, enable IP multicast routing.
<SwitchB> system-view
[SwitchB] multicast routing
[SwitchB-mrib] quit
# Enable IGMP on VLAN-interface 100 (the interface that connects to the receiver host).
[SwitchB] interface vlan-interface 100
[SwitchB-Vlan-interface100] igmp enable
[SwitchB-Vlan-interface100] quit
# Enable PIM-DM on the other interfaces.
[SwitchB] interface vlan-interface 101
[SwitchB-Vlan-interface101] pim dm
[SwitchB-Vlan-interface101] quit
[SwitchB] interface vlan-interface 102
[SwitchB-Vlan-interface102] pim dm
[SwitchB-Vlan-interface102] quit
# On Switch A, enable IP multicast routing, and enable PIM-DM on each interface.
<SwitchA> system-view
