Huawei Quidway S8500 Series - Igmp Timer Query

Command Manual – Multicast Protocol
Quidway S8500 Series Routing Switches Chapter 4 IGMP Configuration Commands
Huawei Technologies Proprietary
4-13
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 lowest IP address on the shared
network segment acts as the querier.
Related command: igmp timer query and display igmp interface.
