Configuring IGMP query and response parameters on an interface
Make sure that the other querier present interval is greater than the IGMP general query interval.
Otherwise the IGMP querier might change frequently on the network.
Make sure that the IGMP general query interval is greater than the maximum response time for IGMP
general queries. Otherwise, multicast group members might be wrongly removed.
The configurations of the maximum response time for IGMP general queries, the IGMP last member query
interval and the IGMP other querier present interval are effective only for IGMPv2 and IGMPv3
To do...
