L2 Multicast Control
IGMP Proxy (RI Mode Only)
Based on IGMP forwarding, the IGMP proxy runs the host part of IGMP on the upstream and router part of IGMP
on the downstream, and replicates multicast traffic across VLANs on devices such as the edge boxes. It reduces
the number of the IGMP control packets transmitted to the core network.
