IGMP
On  the  Advanced / IGMP  page,  you  can allow  the  router to use IGMP  and specify needed 
settings.
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.
