Parameter interval: IGMP other querier present interval in seconds, in the range of 60 to 300.
Description Use the
igmp timer other-querier-present command to configure the IGMP
other querier present interval on the current interface.
Use the
undo igmp timer other-querier-present command to restore the
system default configuration.
By default, the IGMP other querier present interval is [ IGMP query interval ] times
[ IGMP querier robustness variable ] plus [ maximum response time for IGMP
general queries ] divided by two.

The three parameters in the above-mentioned formula default to 60 (seconds), 2
(times) and 10 (seconds) respectively, so the default other querier present interval
= 60 × 2 + 10 / 2 = 125 (seconds).
Related command: timer other-querier-present (IGMP view), igmp timer query, igmp
robust-count, igmp max-response-time, display igmp interface.
Example # Set the other querier present interval to 200 seconds on Ethernet 1/0.
<Sysname> system-view
