Configuration procedure
1. Configure the IP address and subnet mask for each interface as shown in Figure 18. (Details not
shown.)
2. Enable OSPF on the switches in the PIM-DM domain to make sure the network-layer on the PIM-DM
network is interoperable 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 B, enable IP multicast routing globally, enable IGMP on VLAN-interface 100, and
enable PIM-DM on each interface.
<SwitchB> system-view
[SwitchB] multicast routing-enable
[SwitchB] interface vlan-interface 100
[SwitchB-Vlan-interface100] igmp enable
[SwitchB-Vlan-interface100] pim dm
[SwitchB-Vlan-interface100] quit
[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 globally and enable PIM-DM on each interface.
