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