Igmp Version 3 Igmpv2 improved version 1 by adding the ability for a host to signal a desire to leave a multicast group. similarly, igmpv3 has enhancements over version 2. it supports source specific multicast and introduces membership report aggregation. In this video, we dig deeper into the operation of igmp v1, v2 and v3. we also look at various packet captures and understand the benefits of each igmp version.
Igmp Version 3 We are looking into a field issue where the network is configured for igmpv2 but windows appears to be ignoring that and continuing to use igmpv3. things seem to be working in our test lab environment. There are three versions of igmp, version 1, 2, and 3. each of these has unique characteristics. as of this writing, the default igmp version enabled on most cisco devices is version 2. the original specification for igmp was documented in rfc 988 back in 1986. Igmp version 3 adds support for “source filtering”. igmp version 1 and version 2 allow hosts to join multicast groups but they don’t check the source of the traffic. Internet group management protocol (igmp) is used by ipv4 hosts and routers to report their ip multicast group memberships to neighboring multicast routers. a multicast router keeps a list of multicast group memberships for each attached network, and a timer for each membership.

There are three versions of igmp: 1, 2, and 3. the versions don’t change how multicast traffic is forwarded. it only changes how hosts join and leave multicast groups. igmp v1 uses only two messages: membership report and membership query. The internet group management protocol (igmp) is the protocol used by ipv4 systems to report their ip multicast group memberships to neighboring multicast routers. What is igmp? igmp (internet group management protocol) is a host router multicast signalling protocol that provides dynamically registration of the hosts to the desired multicast groups. with igmp, host requests to join to the multicast groups. this join request comes to the dr (designated router).
