Configuration procedure
1. Configure the IP address and subnet mask of each interface as per Figure 39. (Details not shown.)
2. Enable IP multicast routing, PIM-DM, IGMP, and IGMP proxying:
# Enable IP multicast routing on Switch A, PIM-DM on VLAN-interface 101, and IGMP on
VLAN-interface 100.
<SwitchA> system-view
[SwitchA] multicast routing-enable
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] pim dm
[SwitchA-Vlan-interface101] quit
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] igmp enable
[SwitchA-Vlan-interface100] pim dm
[SwitchA-Vlan-interface100] quit
# Enable IP multicast routing on Switch B, IGMP Proxying on VLAN-interface 100, and IGMP on
VLAN-interface 200.
<SwitchB> system-view
[SwitchB] multicast routing-enable
[SwitchB] interface vlan-interface 100
[SwitchB-Vlan-interface100] igmp proxying enable
[SwitchB-Vlan-interface100] quit
[SwitchB] interface vlan-interface 200
[SwitchB-Vlan-interface200] igmp enable
[SwitchB-Vlan-interface200] quit
Verifying the configuration
# Display IGMP information on VLAN-interface 100 of Switch B.
[SwitchB] display igmp interface vlan-interface 100 verbose
