Parameter
seconds: IGMP querier present timer value in second ranging from 1 to 131070. By
default, the value is twice the value of IGMP query message interval, i.e., 120 seconds.
Description
Using igmp timer other-querier-present command, you can configure the timer of
presence of the IGMP querier. Using undo igmp timer other-querier-present
command, you can restore the default value.
On a shared network, i.e., there are multiple multicast routers on the same network
segment, the query router (querier for short) takes charge of sending query messages
periodically on the interface. If other non-queriers receive no query messages within
the valid period, the router will consider the previous query to be invalid and the router
itself becomes a querier.
In IGMP version 1, the selection of a query 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.
For the related commands, see igmp timer query and display igmp interface.
