Multicast provides an efficient way to send data to an interested set of receivers to only one copy of data from the source, by letting the intermediate multicast-routers in the network replicate packets to reach multiple receivers based on a group subscription.

The Multicast settings are applied to all the Edges associated with the Profile. You can choose to override the Multicast settings for an Edge:
  1. In the SD-WAN Service of the Enterprise portal, go to Configure > Edges. The Edges page displays the existing Edges.
  2. Click the link to an Edge or click the View link in the Device column of the Edge. The configuration options for the selected Edge are displayed in the Device tab.
  3. Scroll down to the Routing & NAT category and expand the Multicast area.
  4. The Multicast settings configured for the associated Profile are displayed. If required, you can select the Override check box and modify the Multicast settings.
