1-16 

the maximum response time (the host obtains the value of the maximum response time from the Max 

Response Time field in the MLD query it received). When the timer value comes down to 0, the host 

sends an MLD report to the corresponding IPv6 multicast group.  

An appropriate setting of the maximum response time for MLD queries allows hosts to respond to 

queries quickly and avoids bursts of MLD traffic on the network caused by reports simultaneously sent 

by a large number of hosts when the corresponding timers expire simultaneously.

For MLD general queries, you can configure the maximum response time to fill their Max Response 

time field.  

z 

For MLD multicast-address-specific queries, you can configure the MLD last-member query 

interval to fill their Max Response time field. Namely, for MLD multicast-address-specific queries, 

the maximum response time equals to the MLD last-member query interval.  

Follow these steps to configure MLD queries and responses globally:  

Enter system view 

— 

Enter MLD snooping view 

— 

Configure the maximum 
response time for MLD general 
queries 

max-response-time interval 

Optional 

10 seconds by default  

Configure the MLD 
last-member query interval  

last-listener-query-interval 
interval 

Optional 

1 second by default  

 

Follow these steps to configure MLD queries and responses in a VLAN  

Enter system view 

— 

Enter VLAN view 

vlan vlan-id 

— 

Configure MLD query interval  

mld-snooping query-interval 
interval 

Optional 

125 seconds by default  

Configure the maximum 
response time for MLD general 
queries 

mld-snooping 
max-response-time interval 

Optional 

10 seconds by default  

Configure the MLD 
last-member query interval  

mld-snooping 
last-listener-query-interval 
interval 

Optional 

1 second by default  

 

Make sure that the MLD query interval is greater than the maximum response time for MLD general 

queries; otherwise undesired deletion of IPv6 multicast members may occur.
