DG-BG4300N User Manual 7. Service Setup 7.1 IGMP Configuration Multicasting is useful when the same data needs to be sent to more than one hosts. Using multicasting as opposed to sending the same data to the individual hosts uses less network bandwidth. The multicast feature also enables you to receive multicast video stream from multicast servers.
PAGE 74
DG-BG4300N User Manual IP hosts use Internet Group Management Protocol (IGMP) to report their multicast group memberships to neighboring routers. Similarly, multicast routers use IGMP to discover which of their hosts belong to multicast groups. This device supports IGMP proxy that handles IGMP messages. When enabled, this device acts as a proxy for a LAN host making requests to join and leave multicast groups, or a multicast router sending multicast packets to multicast group on the WAN side.
PAGE 75
DG-BG4300N User Manual Downstream: The interface data from the multicast router are sent to hosts in the multicast group database. Fields in this page: Field Description IGMP Proxy Enable/Disable IGMP proxy feature Proxy Interface The upstream WAN interface is selected here. 7.1.2 MLD Configuration Multicast Listener Discovery (MLD) is a component of the Internet Protocol Version 6 (IPv6) suite.
