Multicasting
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 updating 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>Advanced Features>Multicast.
To enable Multicast, open the multicast screen and select the Enable IGMP Multicast.
