Overview Multicast VLAN

For the traditional multicast-on-demand mode, when in the user-on-demand of different VLANs, each VLAN copies one multicast flow in the VLAN. The multicast-on-demand mode wastes lots of bandwidth.

To solve the problem, you can configure the multicast VLAN mode to make the users in different VLANs share one multicast VLAN. After the multicast VLAN function is enabled, the multicast flow is just transmitted in the multicast VLAN and the multicast VLAN is completely separated from the user VLAN. This not only saves the bandwidth, but also ensures the security.

Multicast VLAN has two kinds: MVR (Multicast VLAN Registration) and MVP (Multicast VLAN Plus).
