Configure Multicast

Learn how to configure multicast in
Prisma SD-WAN
.
Prisma SD-WAN
extends the capabilities of the Layer 3 LAN interface to include multicast. Multicasting is a well-known one-to-many or many-to-many distributed form of network communication. It allows the sender to send single examples of the data packet as streams and distribute those packets only to the hosts interested in receiving that traffic.
Configure LAN multicast on branch site devices running versions 5.6.1 or higher than 5.6.1 but lower than 6.0.1. Configure LAN and/or WAN multicast on devices running 6.0.1 or later versions.
