9.2.5.3 IGMP v2 Snooping Last-Member-Interval
When receive Leave Message from host in IGMP v2, Querier sends Specific Query and
check whether there is Multicast Group Member. Basically, if Membership Report about
First Specific Query does not come, after 1 second, send second Specific Query. If there
is no response also, it deleted from Membership Table. Last-member-interval is the value
to regulate gap between first Specific Query and second Specific Query. By limiting Inter-
val value, IGMP v2 function and fast Leave can be implemented.
To send IGMP Query message and configure the respond time, use the following com-
mand.
Command Mode Description
ip igmp snooping last-member-
query-interval <100-10000>
Configures the time of registering in multicast group
after sending Join message on the system. (unit: ms)
ip igmp snooping vlan VLANS
last-member-query-interval
<100-10000>
Global
Configures the time of registering in multicast group
after sending Join message on a VLAN interface.
If you configure ip igmp snooping fast-leave, it is meaningless to register time as multi-
cast group.
To release the waiting time for respond after sending IGMP Query message, use the fol-
lowing command.
Command Mode Description
no ip igmp snooping last-
member-query-interval
Returns to the default time of registering Join message
in multicast group after sending it.
no ip igmp snooping vlan
VLANS last-member-query-
interval
