Tcp Ip Protocol Questions Medium
The purpose of the Internet Group Management Protocol version 2 (IGMPv2) in the TCP/IP Protocol is to enable hosts on a local network to report their multicast group memberships to neighboring routers. IGMPv2 allows routers to efficiently manage multicast traffic by keeping track of which hosts are interested in receiving multicast packets. This protocol is essential for the functioning of IP multicast, where a single packet can be sent to multiple hosts simultaneously. IGMPv2 ensures that multicast traffic is only forwarded to the networks where there are interested receivers, reducing unnecessary network congestion and optimizing bandwidth utilization.
