Transmission of multicast traffic using PIM and IGMP protocols

Kaspersky SD-WAN supports transmission of multicast traffic between CPE devices and external network devices using the PIM and IGMP protocols. You can specify the basic settings of the PIM protocol on CPE devices, for example, the rendezvous points to be used, and then create multicast interfaces for interaction with other devices. Previously created network interfaces are used as multicast interfaces.

If PIM connectivity is established between CPE devices and rendezvous points are defined for these devices, multicast interfaces can receive requests from clients over IGMP. These requests contain IP addresses of sources from which clients want to receive multicast traffic packets. When sources send multicast packets to a rendezvous point, clients receive these packets.

If necessary, you can use the PIM protocol to connect CPE devices to external routers. To do so, you must enable the PIM protocol on the mulitcast interface to which the external router is connected.
