To speed up the response of hosts to MLD queries and avoid simultaneous timer expirations causing
MLD report traffic bursts, set a proper value for the maximum response delay:
•
The maximum response delay for MLD general queries is set by the
max-response-time
command.
•
The maximum response delay for MLD multicast-address-specific queries equals the MLD
last-listener query interval.
