z 

For MLD general queries, you can configure the maximum response delay to fill their Maximum 

Response Delay field. 

z 

For MLD multicast-address-specific query messages, you can configure the last listener query 

interval to fill their Maximum Response Delay field. That is to say, the maximum response time of 

MLD general query messages equals the last listener query interval. 

When multiple multicast routers exist on the same subnet, the MLD querier is responsible for sending 

MLD query messages. If a non-querier router receives no MLD query from the querier within the “other 

querier present interval”, it will assume that the querier has failed and a new querier election process is 

launched. Otherwise, the non-querier will reset “other querier present timer”.
