IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership
in a multicast group - it is not used to carry user data. The EMG2926-Q10A supports both IGMP
version 1 (I GMP- v1 ) and IGMP version 2 (I GM P- v2 ).
At start up, the EMG2926-Q10A queries all directly connected networks to gather group
membership. After that, the EMG2926-Q10A periodically updates this information. IP multicasting
can be enabled/disabled on the EMG2926-Q10A WAN interface in the Web Configurator (W AN ).
Select N one to disable IP multicasting on these interfaces.
