seconds: Other querier present interval in seconds, in the range of 1 to 131,070. 

Use the igmp timer other-querier-present command to configure the other querier present interval, 

namely the length of time a non-querier waits before it assumes that the current IGMP querier is down.  

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

By default, the other querier present interval is twice the value of IGMP query interval, that is, 120 

seconds if the IGMP query interval has not been manually configured.  

On a multi-access network, that is, the same network segment including multiple multicast routers, the 

query router (known as querier) is responsible for sending general query messages periodically through 

the VLAN interface. If a non-queriers receive no query messages within the other querier present 

interval, it assumes that the current querier is down and a new querier election process takes place. 

In IGMP version 1, the selection of a querier is determined by the multicast routing protocol. In IGMP 

version 2, the router with the lowest IP address on the shared network segment acts as the querier.
