1.IGMP
IGMP listening (Internet Group Management Protocol Snooping) is a multicast constraint mechanism running on layer II devices to manage and control multicast groups. By configuring multicast VLAN, the port of the switch is added to multicast VLAN, so that users in different VLAN VLAN receive multicast data, and the multicast stream is transmitted and only transmitted in one multicast VLAN, thus saving bandwidth. And because of the multicast VLAN with the users. The VLAN is completely isolated, with both security and bandwidth guaranteed.
