This article introduces how IGMP Snooping works, and the functions and applications of IGMP Snooping.
Internet Group Management Protocol (IGMP) snooping sounds like an invasion of privacy or a type of hacking attack, but it is actually an important feature in multimedia broadcasts. IGMP snooping aims to decrease broadband and memory usage, and helps a broadcast remain powerful by limiting the amo...

A. IGMP snooping is not active for VLAN 120 because the IGMP feature has not been enabled on the switch with the feature igmp command. B. The IGMP snooping querier for VLAN 120 is not in a running stat...
The role of IGMP is clearly defined: The communication protocol is always used wheresuch as the internet. Classic deployment scenarios arethat run over multipoint connections – such asor. Not every client should have to be supplied with the required data stream individually, as this would quickl...
The IPTV provider can deliver content to users in unicast or multicast streaming. In multicast, the provider sends many users a single piece of content. The Internet Group Management Protocol (IGMP) makes multicast streaming easy. It is useful when an IPTV provider needs to deliver the same dat...

IGMPstands for “Internet Group Management Protocol” – the IPv4 protocol for managing multicast groups. The counterpart for IPv6 connections is the “Multicast Listener Discovery” (MLD) protocol. What is IGMP snooping? Multicast packets often pass through multiple stations on their way to the tar...
Examples: RTMP, HLS, IGMP,RTMPS. Codec is a way to compress video. Examples: aac, h264, mp3. A special digital container is how compressed video is being packed into bytes for transmission from one participant to another (over a certain protocol). ...
Normally, SM is a better approach than PIM DM, but we don't even know if multicast routing is even configured. It's possible (I believe), DM might be defined on a few interfaces just for an IGMP querier to support IGMP snooping on those VLANs. For such a usage case, possib...
