• For IGMP group-specific queries, you can configure the IGMP last member query interval to fill their
Max Response time field. Namely, for IGMP group-specific queries, the maximum response time
equals to the IGMP last member query interval.
When multiple multicast routers exist on the same subnet, the IGMP querier is responsible for sending
IGMP queries. If a non-querier router receives no IGMP query from the querier within the “other querier
present interval”, it will assume the querier to have expired and a new querier election process is
launched; otherwise, the non-querier router will reset its “other querier present timer”.
