The following ESM multicast replication modes are supported:
per-host replication
This mode supports multicast packet replication per subscriber host. Each multicast packet destination uses an individual host source MAC address. The multicast traffic is unicast to the host by replacing the destination MAC from a multicast MAC with the host MAC address. A typical use case for per-host replication is for PPoE subscribers.
per-SAP replication
When all subscribers use this replication mode on a single SAP, the system ensures that no more than one multicast packet is sent per (S,G). This mode is used by default when another replication mode is not configured.
per-SPI replication
In this mode, the multicast packet replication depends on the number of SLA profile instances configured for the subscriber hosts. A single copy of the multicast packet is sent to hosts that use the same SLA profile, and the multicast packet is replicated for each host that uses a different SLA profile. For example, if all subscriber hosts use the same SLA profile, only one multicast packet is sent from a specific (S,G). However, if the subscriber hosts use three different SLA profiles, three multicast packets are sent.
multicast redirection
In this mode, the multicast packets are sent to all the subscribers using a dedicated VLAN.
