2.3.1 Establishing the Configuration Task

Applicable Environment
In traditional multicast transmission mode, a router must copy multicast data for each user VLAN
and send all copies to the downstream device when users in different VLANs request the program
provided by the same multicast source. This mode wastes network bandwidth and adds workload
on the router.
Multicast VLAN replication helps to manage and control the multicast source and the multicast
group members. This function enables users in different VLANs to receive the same multicast
flow and saves bandwidth.
In multicast VLAN replication implementation, VLANs are classified into multicast VLANs
and multiple user VLANs. The S2700 interface connected to a multicast source belongs to a
multicast VLAN, and interfaces connected to members of a multicast group belong to user
VLANs. The multicast VLAN aggregates multicast flows, and user VLANs receive data from
the multicast VLAN.
