Advanced>Multicast
IGMP [=Internet Group Management Protocol] Multicast enables communication
between a single sender and multiple receivers on a network. It is used when data
needs to be sent from one to many devices. Typical uses might include the updat-
ing of mobile personnel from a home office or the periodic publishing of an online
newsletter. Multicasting provides efficiencies which enable it to use less network
bandwidth than the sending of the same data by other means [e.g. SMTP].
To access Multicasting, click on Advanced>Multicast.
To enable Multicast, open the multicast screen and select the Enable IGMP Multicast.
If you have multiple connections setup on your modem you will be able to choose
which connection to enable IGMP Multicast for.
Click the Apply button to save the settings.
