Configuring IGMP Snooping

Copyright © 2017, Juniper Networks, Inc.
No reports are sent on host-side interfaces by IGMP snooping in proxy mode. IGMP
snooping processes reports received on these interfaces and sends group-specific queries
onto host-side interfaces when it receives a leave message on the interface. Host-side
interfaces do not generate periodic general queries, but forwards or floods general queries
received from multicast-router interfaces.
If a group is removed from a host-side interface and this was the last host-side interface
for that group, a leave is sent to the multicast-router interfaces. If a group report is received
on a host-side interface and this was the first host-side interface for that group, a report
is sent to all multicast-router interfaces.

Understanding Multicast Snooping
IGMP snooping on a VLAN is only allowed for the legacy
there is a specific bridge domain configuration that determines the VLAN-specific
configuration for IGMP snooping.

Understanding Multicast Snooping
To configure Internet Group Management Protocol (IGMP) snooping, include the
igmp-snooping statement:
igmp-snooping {
immediate-leave;
interface interface-name {
group-limit limit;
host-only-interface;
immediate-leave;
multicast-router-interface;
static {
group ip-address {
source ip-address;
}
}
}
proxy {
