Configuration procedure
1. Configure IP addresses and unicast routing
Configure the IP address and subnet mask of each interface according to Figure 33. Th
e detailed
configuration steps are omitted here.
Configure the OSPF protocol for interoperation on the PIM network. Ensure the network-layer
interoperation on the PIM network and dynamic update of routing information among the switches
through a unicast routing protocol. The detailed configuration steps are omitted here.
2. Enable IP multicast routing, and enable PIM-DM and IGMP
# Enable IP multicast routing on Switch A, enable PIM-DM on each interface, and enable IGMP on
VLAN-interface 100.
<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
# Enable IP multicast routing on Switch B, enable PIM-DM on each interface, and enable IGMP on
VLAN-interface 200.
<SwitchB> system-view
[SwitchB] multicast routing-enable
[SwitchB] interface vlan-interface 200
[SwitchB-Vlan-interface200] igmp enable
[SwitchB-Vlan-interface200] pim dm
