IGMP Snooping

Ever heard of IGMP? It is an advanced option on the majority of the routers. In this article, you will learn how exactly IGMP Snooping actually works. You will also be able to learn how and when to use it. This article is written in very simple words and no technical terms have been used in it. The main objective of writing this article is to make the IGMP Snooping as simple as possible for the readers.


In simple words, we can say that once you have enabled IGMP, your access point starts acting as mailman or gate for the multicast traffic. Some networks have a lot of multicast traffic and the result is poor performance of the entire network. IGMP Snooping can be very helpful in this regard. It is the job of the router to decide which devices will receive the applicable multicast traffic in order to improve the overall performance of the network. But, as stated above, this situation is true for networks having plenty of multicasts traffics. IGMP Snooping is not recommended for networks having little or almost no multicast traffic.
