3.
Set the IGMP querier's
robustness variable.
igmp robust-count
count
By default, the IGMP querier's
robustness variable is 2.
4. Set the IGMP startup query
interval.
igmp startup-query-interval
interval
By default, the IGMP startup
query interval equals one quarter
of the IGMP general query
interval.
5. Set the IGMP startup query
count.
igmp startup-query-count
count
By default, the IGMP startup
query count equals the IGMP
querier's robustness variable.
6. Set the IGMP general query
interval.
igmp query-interval
interval
By default, the IGMP general
query interval is 125 seconds.
7.
Set the IGMP last member
query interval.
igmp
last-member-query-interval
interval
By default, the IGMP last member
query interval is 1 second.
8.
Set the IGMP last member
query count.
igmp last-member-query-count
count
By default, the IGMP last member
query count equals the IGMP
querier's robustness variable.
9. Set the maximum response
time for IGMP general
queries.
igmp max-response-time
time
By default, the maximum
response time for IGMP general
queries is 10 seconds.
10.
Set the IGMP other querier
present timer.
igmp
other-querier-present-interval
interval
By default, the IGMP other querier
present timer is
calculated by
using the following formula:
[ IGMP general query interval ] ×
[ IGMP robustness variable ] +
[ maximum response time for
IGMP general queries ] / 2.
Enabling fast-leave processing
This feature enables an IGMP querier to send leave notifications to the upstream without sending
group-specific or group-and-source-specific queries after receiving a leave message. Use this
feature to reduce leave latency and to preserve the network bandwidth.
The fast-leave processing configuration takes effect only when the device runs IGMPv2 or IGMPv3.
To enable fast-leave processing:
