Setting the MLD last listener query interval
A receiver host starts a report delay timer for an IPv6 multicast group when it receives an MLD
multicast-address-specific query for the group. 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 group.
The MLD last listener query interval defines the maximum response time advertised in MLD
multicast-address-specific queries. Set an appropriate value for the MLD last listener query interval
to speed up hosts' responses to MLD multicast-address-specific queries and avoid MLD report traffic
bursts.
Configuration restrictions and guidelines
When you set the MLD last listener query interval, follow these restrictions and guidelines:
•
The Layer 2 device does not send an MLD multicast-address-specific query if it receives an
MLD done message from a port enabled with fast-leave processing.
•
You can set the MLD last listener query interval globally for all VLANs and VSIs in
MLD-snooping view, for a VSI in VSI view, or for a VLAN in VLAN view. For a VSI, the
VSI-specific configuration takes priority over the global configuration. For a VLAN, the
VLAN-specific configuration takes priority over the global configuration.
