5.1 IGMP Overview
As a TCP/IP protocol responsible for IP multicast group member management, the
Internet Group Management Protocol (IGMP) is used by IP hosts to establish and
maintain their multicast group memberships to immediately neighboring multicast
routers.

5.1.1 IGMP Versions

So far, there are three IGMP versions:
IGMPv1 (documented in RFC 1112)
IGMPv2 (documented in RFC 2236)
IGMPv3 (documented in RFC 3376)
All IGMP versions support the Any-Source Multicast (ASM) model. In addition, IGMPv3
can be directly used to implement the Source-Specific Multicast (SSM) model.
Note:
For more information about the ASM and SSM models, see Multicast Overview of the
IP Multicast Volume.
