group-source-specific query (IGMPv3) message to determine if there is still any host in-
terested in receiving the traffic. If there is no reply, the querier stops forwarding the mul-
ticast traffic. However, IGMP messages may get lost for various reasons, so you can
specify the number of sending query messages and its interval.
To specify the number of sending group-specific or group-source-specific query messag-
es, use the following command.
ip igmp last-member-query-
count <2-7>
Specifies a last member query count.
2-7: last member query count value (default: 2)
no ip igmp last-member-query-
count
Deletes a specified last member query count.
To specify the interval to send group-specific or group-source-specific query messages,
use the following command.
ip igmp last-member-query-
interval <1000-25500>
Specifies a last member query interval.
1000-25500: last member query interval
(default: 1000 milliseconds)
no ip igmp last-member-query-
interval
Deletes a specified last member query interval.
IGMP Unsolicited Report Interval
When one of its hosts joins a multicast address group to which none of its other hosts be-
long, sends unsolicited group membership reports to that group. You can specify the in-
terval to send this unsolicited report messages as many as the configured QRV value.
To specify the interval to send unsolicited report messages, use the following command.
ip igmp unsolicited-report-
interval <1-18000>
Specifies an unsolicited report interval.
1-18000: unsolicited report interval
(default: 10 seconds)
ip igmp proxy unsolicited-
report-interval <1000-25500>
Specifies an unsolicited report interval.
1000-25500: unsolicited report interval
(default: 1000 ms)
no ip igmp [proxy] unsolicited-
report-interval
Deletes a specified unsolicited report interval.
10.1.2.4 IGMP Immediate Leave
Normally, a querier sends a group-specific or group-source-specific query message upon
receipt of a leave message from a host. If you want to set a leave latency as 0 (zero), you
can omit the querying procedure. When the querying procedure is omitted, the router im-
mediately removes the interface from the IGMP cache for that group, and informs the
multicast routing protocols.
