Operation Manual – Multicast
H3C S7500E Series Ethernet Switches
IGMP is required on Router A, IGMP Snooping is required on Switch A, and
Router A will act as the IGMP querier on the subnet.
Perform the following configuration so that multicast data can be forwarded
through Ethernet 2/0/3 and Ethernet 2/0/4 even if Host A and Host B temporarily
stop receiving multicast data for some unexpected reasons.
