PIM and IGMP in global domain

Protocol Independent Multicast (PIM) and Internet Group Management Protocol (IGMP) messages for multicast data delivery are supported. ACX Series routers are used as a leaf in the multicast distribution tree so that subscribers in the global domain can directly connect to the ACX Series routers through IPv4 interfaces. ACX Series routers can also be used as a branch point in the tree so that they are connected to other downstream ACX Series or MX Series routers and send multicast data according to the membership established through the PIM or IGMP messaging.
