MLD VLAN Settings
To configure MLD on a specific VLAN:
STEP 1 Click Multicast > IPv6 Multicast Configuration > MLD VLAN Settings.
The following fields are displayed for each VLAN on which is enabled:
• Interface Name—VLAN for which MLD information is being displayed.
• Router MLD Version—Version of MLD 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)—Enter the 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. Found only found on SG500X/
SG500XG devices.
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.
