MLD Snooping Query Response Time
MLDv1/v2 membership query messages include the maximum query response time field.
This field specifies the maximum time allowed before sending a responding report. The
maximum query response time allows a router to quickly detect that there are no more
hosts interested in receiving multicast traffic.
To specify a maximum query response time advertised in general query messages, use
the following command.
Command
Mode
Description
ipv6 mld snooping query-max-
response-time
<1-240>
Interface
[VLAN]
Specifies a maximum query response time.
1-240: maximum response time (default: 10 seconds)
To delete a specified maximum query response time, use the following command.
Command
Mode
Description
no ipv6 mld snooping query-
max-response-time

resets the default.

MLD Snooping Fast Leave
Fast-leave can be used to speed up the reaction to MLD leave announcements.
This minimizes the leave latency of group memberships on an interface, as the switch
does not send group-specific queries. As a result, the group entry is removed from the
forwarding table as soon as a group done message is received.
To enable the MLD snooping fast leave, use the following command.
Command
Mode
Description
ipv6 mld snooping fast-leave
Interface
[VLAN]
Enables the MLD snooping fast leave.
