Release Information
Statement introduced in Junos OS Release 8.3.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Description
When this statement is enabled on a routing device running IGMP version 2 (IGMPv2),
after the routing device receives a leave group membership message from a host
associated with the interface, the routing device immediately removes the group
membership from the interface and suppresses the sending of any group-specific queries
for the multicast group.
When this statement is enabled on a routing device running IGMP version 3 (IGMPv3),
after the routing device receives a report with the type BLOCK_OLD_SOURCES, the routing
device suppresses the sending of group-and-source queries but relies on the Junos
OS-supported host tracking mechanism to determine whether or not it removes a
particular source group membership from the interface.
NOTE:
When issuing this command on IGMPv2 interfaces, ensure that the
IGMP interface has only one IGMP host connected. If more than one IGMPv2
host is connected to a LAN through the same interface, and one host sends
a done message, the routing device removes all hosts on the interface from
the multicast group. The routing device loses contact with the hosts that
properly remain in the multicast group until they send join requests in response
to the next general multicast listener query from the router.
