2.2.6 Configuring IGMP Querier

In an IGMP-enabled network, a specific query multicast router or Layer 3 multicast
switch is responsible for sending IGMP query packets.
However, the Layer 2 multicast switch does not support the IGMP feature. Therefore,
the Layer 2 multicast switch cannot implement the querier feature and cannot send
general group query packets. Through configuring IGMP Snooping queriers, you can
enable the Layer 2 multicast switch to send general group query packets actively at the
data link layer, and thereby establish and maintain the multicast forwarding entries.
Additionally, you can enable the Layer 2 switch to send the source addresses,
maximum query time and query interval of general group query packets,

2.2.7 Configuring Multicast VLAN

In old multicast mode, when users in different VLANs order the same multicast group,
the multicast stream is copied to each of the VLANs. This mode wastes a lot of
bandwidth.
