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.
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.
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
Use the no version to restore the default, 10-tenths of a second (1 second).
See ipv6 mld last-member-query-interval.
Use to set the time, in the range 1–400 seconds, that the interface waits for queries
from the current querier before sending query messages to assume responsibility of
querier.
Example
host1:boston(config-if)#ipv6 mld querier-timeout 200
