Summary of Multicast VLAN Replication Configuration Tasks
Multicast VLAN replication can be configured in different methods depending on the application scenario. Table 14-1 lists multicast VLAN replication configuration tasks.
Task | Description |
---|---|
When user VLAN-based multicast VLAN replication is configured on a switch, the upstream device only needs to send one copy of multicast data to the switch. The switch then replicates multicast data and sends the data to multiple user VLANs. This saves bandwidth between the upstream device and the switch. |
|
By binding user VLANs to a multicast VLAN on a user-side interface, you can implement multicast service isolation on the interface while allowing multicast data replication to user VLANs. For example, when multiple ISPs provide multicast services on a network, you can configure this function to ensure that data of an ISP is forwarded only to the users who have subscribed to the services of the ISP. |
