IGMP
On the
Advanced / IGMP
page, you can allow the router to use IGMP.
IGMP is used for managing multicast traffic (transferring data to a group of destinations). This
protocol allows using network resources for some applications, e.g., for streaming video, more
efficiently.
Figure 137. The
Advanced / IGMP
page.
The following elements are available on the page:
Parameter
Description
Enable
Move the switch to the right to enable IGMP.
IGMP version
Select a version of IGMP from the drop-down list.
Interface
From the drop-down list, select a connection of the Dynamic IPv4 or
Static IPv4 type for which you need to allow multicast traffic (e.g.
streaming video).
IGMP Snooping
The IGMP snooping function allows limiting multicast traffic for
devices connected to the Ethernet ports of the router.
If the switch is moved to the right, multicast traffic is forwarded
only to the devices which require it.
If the switch is moved to the left, multicast traffic is forwarded to all
devices connected to the Ethernet ports of the router.
After specifying the needed parameters, click the
APPLY
button.
