To configure IGMP on a specific VLAN, complete the following steps:
Procedure
Step 1 | Click Multicast > IPv4 Multicast Configuration > IGMP VLAN Settings.
The following fields are displayed for each VLAN on which IGMP is enabled:
-
Interface Name—VLAN on which IGMP snooping is defined.
-
Router IGMP Version—Version of IGMP Snooping.
-
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 can’t 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 aren’t forwarded on the interface. The default value of 0 means that 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.

Step 2 | Select an interface, and click Edit. Enter the values of the fields described above. |
Step 3 | Click Apply. The Running Configuration file is updated. |
