12.6 IGMP Snooping Screen

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.

DESCRIPTION
Select IGMPv1/v2 to enable multicasting. This applies to traffic routed
from the WAN to the LAN.
Select None to disable this feature. This may cause incoming traffic to be
dropped or sent to all connected network devices.
Select this option to have the NBG-419N switch to bridge mode
automatically when the NBG-419N gets a WAN IP address in the range of
192.168.x.y (where x and y are from zero to nine) no matter what the LAN
IP address is.
Click Apply to save your changes back to the NBG-419N.
Click Reset to begin configuring this screen afresh.
