Operation Manual – Multicast
H3C S5500-EI Series Ethernet Switches
IGMP is required on Router A, and IGMP Snooping is required on Switch A.
Router A is the IGMP querier.
Switch A's GigabitEthernet 1/0/1 belongs to VLAN 1024, GigabitEthernet 1/0/2
through GigabitEthernet 1/0/4 belong to VLAN 11 through VLAN 13 respectively,
and Host A through Host C are attached to GigabitEthernet 1/0/2 through
GigabitEthernet 1/0/4 of Switch A.
Configure the multicast VLAN feature so that Router A just sends multicast data to
VLAN 1024 rather than to each VLAN when the three hosts attached to Switch A
need the multicast data.

III. Configuration procedure
1) Configure an IP address for each interconnecting interface
Configure an IP address and subnet mask for each interface as per
detailed configuration steps are omitted here.
2) Configure Router A
# Enable IP multicast routing, enable PIM-DM on each interface and enable IGMP on
GigabitEthernet 1/0/1.
