Description
Determines whether the computer forwards IP multicasts.
Multicasting enables hosts to send a datagram to multiple recipients in a single operation. To receive multicasts, recipients join a host group that has a single IP destination address.
IP multicasts are forwarded across networks by multicast routers that reside with, or are separate from, Internet gateways. The originating host transmits the IP multicast datagram as a local network multicast to all immediately neighboring members of the destination host group. Then, multicast routers on the local network forward the datagram to all other networks.
