interval: IGMP other querier present interval, in the range of 60 to 300.  

Use the timer other-querier-present command to configure the IGMP other querier present interval 

globally.  

Use the undo timer other-querier-present command to restore the system default.  

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.  

 

By default, the three parameters in the above-mentioned formula are 60 (seconds), 2 (times) and 10 

(seconds) respectively, so the IGMP other querier present interval = 60 × 2 + 10 / 2 = 125 (seconds).
