3. Configure the IGMP querier's
robustness variable.
robust-count robust-value
2 by default.
A higher robustness variable
makes the IGMP querier more
robust, but results in longer
multicast group timeout time.
4. Configure the startup query
interval.
startup-query-interval interval
By default, the startup query
interval is one-quarter of the "IGMP
general query interval."
5. Configure the startup query
count.
startup-query-count value
By default, the startup query count
is the same as the IGMP querier's
robustness variable.
6. Configure the IGMP general
query interval.
timer query interval 60 seconds by default.
7. Configure the maximum
response time for IGMP
general queries.
max-response-time interval 10 seconds by default.
8. Configure the IGMP
last-member query interval.
last-member-query-interval
interval
1 second by default.
9. Configure the other querier
present interval.
timer other-querier-present
interval
By default, the other querier
present interval is [ IGMP general
query interval ] × [ IGMP
robustness variable ] + [ maximum
response time for IGMP general
queries ] / 2.
