An example of the effect of IGMP snooping on the traffic in a LAN. IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP) network traffic to control delivery of IP multicasts. Network switches with IGMP snooping listen in on the IGMP conversation between hosts and routers and maintain a map of which links need ...
Switches featuring IGMP snooping also derive useful information by observing these IGMP transactions. Protocol Independent Multicast (PIM) is then used between the local and remote multicast routers to direct multicast traffic from hosts sending multicasts to hosts that have registered through IGMP to receive them. IGMP operates on the network ...
Each host that wants to be a receiving member of a multicast group (i.e. receive data corresponding to a particular multicast address) must use IGMP to join. Adjacent routers also use this protocol to communicate. In unicast routing, each router examines the destination address of an incoming packet and looks up the destination in a table to ...
