WebSep 21, 2024 · Enabling IGMP snooping on a layer 2 switch in a LAN segment in which no layer 3 switch exists can result in intermittent multicast connectivity and severe packet loss. Multicasting with Layer 3 switches is much more efficient than with Layer 2 switches because it identifies the multicast packet and sends it only to the intended receivers.

WebPacket loss is usually caused by network congestion where packets are sent faster than the receiver or switch can process. Conventional ethernet silently drops packets and expects retransmission if data is sent too fast. It is this packet drop that causes huge hits to latency and throughput.
