Internet Group Management Protocol (IGMP; Defined in RFC 1112 ) is a protocol that allows a host to advertise its multicast group membership to neighboring switches and routers. IGMP is a standard protocol used by the TCP/IP protocol suite to achieve dynamic multicasting.Click to see full answer. Similarly, it is asked, what is IGMP used for?The Internet Group Management Protocol (IGMP) is a communications protocol used by hosts and adjacent routers on IPv4 networks to establish multicast group memberships. IGMP is an integral part of IP multicast.Likewise, should I enable IGMP? IGMP proxying should be left enabled unless it causes problems. This allows the router to convert Multicast traffic into Unicast traffic, allowing for the network especially wireless devices, to work more efficiently. Also asked, what is IGMP snooping and why would I need it? IGMP Snooping is a feature for switches to learn what multicast groups are needed on which ports. Routers not handling multicast routing don’t care. That said, without an mrouter in the network, you need to configure one (or more) igmp queriers. The benefit is that multicast traffic goes only where it belongs.What is the difference between IGMP v2 and v3? IGMP Versions Differences IGMPv2 improves over IGMPv1 by adding the ability for a host to signal desire to leave a multicast group and IGMPv3 improves over IGMPv2 mainly by adding the ability to listen to multicast originating from a set of source IP addresses only.
