Configuring parameters for MLD general queries and
responses
CAUTION:
To avoid mistakenly deleting IPv6 multicast group members, make sure the MLD general query
interval is greater than the maximum response time for MLD general queries.
You can modify the MLD general query interval for a VLAN based on the actual network conditions.
A receiver host starts a report delay timer for each IPv6 multicast group that it has joined when it
receives an MLD general query. This timer is set to a random value in the range of 0 to the maximum
response time advertised in the query. When the timer value decreases to 0, the host sends an MLD
report to the corresponding IPv6 multicast group.
Configuration restrictions and guidelines
When you configure parameters for MLD general queries and responses, follow these restrictions
and guidelines:
•
Set an appropriate value for the maximum response time for MLD general queries to speed up
hosts' responses to MLD general queries and avoid MLD report traffic bursts.
•
You can set the maximum response time for MLD general queries globally for all VLANs in
MLD-snooping view or for a VLAN in VLAN view. For a VLAN, the VLAN-specific configuration
takes priority over the global configuration.
