Changes in MLD Snooping timers configuration, such as: Query Robustness, Query Interval
etc. do not take effect on timers which already created.
MLD Interface Settings
An interface that is defined as a Multicast router port receives all MLD packets (reports and
queries) as well as all Multicast data.
To configure an interface as a Multicast router interface:
Click Multicast > IPv6 Multicast Configuration > MLD Interface Settings.
The following fields are displayed for each interface on which MLD is enabled:
•
Router MLD Version—MLD version of the Multicast router.
•
Query Robustness—Enter the number of expected packet losses on a link.
•
Query Interval (sec)—Interval between the general queries to be used if this device is
the elected querier.
•
Query Max Response Interval (sec)—Delay used to calculate the Maximum
Response Code inserted into the periodic general queries.
•
Last Member Query Interval (msec)—Maximum Response Delay to be used if the
device cannot read Max Response Time value from group-specific queries sent by the
elected querier.
•
Multicast TTL Threshold—Enter the Time-to-Live (TTL) threshold of packets being
forwarded on an interface.
Multicast packets with a TTL value less than the threshold are not forwarded on the
interface.
The default value of 0 means all Multicast packets are forwarded on the interface.
A value of 256 means that no Multicast packets are forwarded on the interface.
Configure the TTL threshold only on border routers. Conversely, routers on which you
configure a TTL threshold value automatically become border routers.
To configure an interface, select it and click Edit. Enter the fields that are described above.
Click Apply. The Running Configuration file is updated.
