Multicast Routing


Overview

A multicast routing is a networking method for efficient distribution of one-to-many traffics. In ZStack, VPC vRouters receive multicast information sent by multicast sources and forward the information to VM instances to realize one-to-many connections on senders and receivers.
  • ZStack allows you to use VM instances as the multicast information receivers, and to use VPC vRouters as multicast routers to participate in the multicast routing message exchanges.
  • VPC vRouters support the PIM-SM/PIM-SSM protocol. In the PIM-SM protocol, RP routers are the key devices in the PIM-SM domain. You can either manually configure RP addresses or dynamically elect or assign RP addresses according to the BSR mechanism.
The multicast routing topology is shown in Multicast Routing Topology.
