Overview of IGMP

Overview of IGMP

IGMP a signaling mechanism that sets up and maintains multicast member relationships between routers and their directly connected IP hosts.

IGMP implements the following functions on the host side and router side:
  • On the host side, IGMP allows hosts to dynamically join and leave multicast groups anytime and anywhere.


    A host's operating system (OS) determines the IGMP version that the host supports.

  • On the router side, IGMP enables a router to determine whether multicast receivers of a specific group exist. Each host stores information about only the multicast groups it joins.

IGMP has three versions, as listed in Table 3-1:
