In the per-SLA Profile Instance (SPI) replication mode, a multicast stream is transmitted for the subscriber host SLA profile for each registered multicast group (channel). As a result, multiple copies of the same multicast stream are transmitted over the same SAP. The multicast packet replication depends on the number of SLA profile instances configured for the subscriber. For example, if the subscriber hosts use three SLA profiles, the (S,G) is replicated three times. But if the hosts use the same SLA profile, the (S,G) is replicated only once.
MCAC is supported for per-SPI replication.
Multicast traffic flows on the SAP queue and each copy of the multicast stream use the same multicast destination MAC address.
The per-SPI replication mode can be enabled per subscriber:
in classic CLI, using the per-spi-replication command in the following contexts:
config>subscriber-mgmt>igmp-policy
config>subscriber-mgmt>mld-policy (IPv6)
in MD-CLI, using the replication command in the following contexts:
configure subscriber-mgmt igmp-policy
configure subscriber-mgmt mld-policy
