IGMP
The Internet Group Management Protocol (IGMP) is an internal protocol of the
Internet Protocol (IP) suite. IP manages multicast traffic by using switches,
routers, and hosts that support IGMP. Enabling IGMP allows the ports to detect
IGMP queries and report packets and manage IP multicast traffic through the
switch. IGMP have three fundamental types of message as follows:
