Juniper JUNOSE 11.0.X MULTICAST ROUTING Configuration Manual page 211

ipv6 mld immediate-leave
CAUTION: Issue this command only on MLD interfaces to which one MLD host is
connected. If more than one MLD host is connected to a LAN through the same
interface, and one host sends a done message, the router removes all hosts on the
interface from the multicast group. The router loses contact with the hosts that should
remain in the multicast group until they send join requests in response to the router's
next general multicast listener query.
ipv6 mld last-member-query-interval
The method that the router uses to remove hosts from multicast groups
The time interval at which the querier sends multicast listener queries
The time that a querier waits before sending a new query to hosts from which
it receives multicast listener done messages
The time that a non-querier waits for queries from the current querier before
sending query messages to assume responsibility of querier
The time that a host can take to reply to a query (maximum response time)
The number of times that the router sends each MLD message from this interface
Use to specify that, when the router receives a multicast listener done message
from a host associated with this interface, the router immediately removes that
host from the multicast group.
Use the MLD-Immediate-Leave RADIUS attribute (VSA 26-100) in RADIUS
Access-Accept messages as an alternative method of configuring this value. The
RADIUS setting takes precedence over a CLI setting.
Example
host1:boston(config-if)#ipv6 mld immediate-leave
Use the no version to restore the default behavior, in which the router removes
a host from a multicast group if that host does not return a multicast listener
report within a certain length of time after receiving a multicast listener query
from the router.
See ipv6 mld immediate-leave.
Use to specify the last-member-query-interval value, in the range 1–255 tenths
of a second. When the router receives an MLDv1 leave message or an MLDv2
state change report, it sends out a query and expects a response within the time
specified by this value.
Using a lower value allows members to leave groups more quickly.
Example
host1:boston(config-if)#ipv6 mld last-member-query-interval 90
