IGMP messages to be exchanged (IGMPv2 only):

Statically configure an interface as a switching interface toward a multicast router

IGMP Snooping on EX Series Switches Overview on page 2315
IGMP snooping regulates multicast traffic in a switched network. With IGMP snooping
enabled, the EX Series switch monitors the IGMP transmissions between a host (a network
device) and a multicast router, keeping track of the multicast groups and associated
member interfaces. The switch uses that information to make intelligent
multicast-forwarding decisions and forward traffic to the intended destination interfaces.
You can configure IGMP snooping on one or more VLANs to allow the switch to examine
IGMP packets and make forwarding decisions based on packet content. By default, IGMP
snooping is enabled on EX Series switches.
To enable IGMP snooping and configure individual options using the J-Web interface:
