IGMP group query message after it receives the IGMP Leave message from the
host. the value range is 2 to 5. The default value is 2.
Description
Use the
igmp robust-count
command to set the number of times the IGMP
query router sends IGMP group query message after it receives the IGMP Leave
message from the host.
Use the
undo igmp robust-count
command to restore the default value.

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
Use the
igmp timer other-querier-present
command to configure the timer of
presence of the IGMP querier.
Use the
undo
igmp timer other-querier-present
command to 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 smallest IP address on the shared
network segment acts as the querier.
