Global configuration mode
The no form of this command restores the default age interval to 260 seconds.
When a device receives a group membership report it makes an entry for that group in the MLD group table. You can configure the ipv6 multicast age-interval to specify how long the entry can remain in the table before the device receives another group membership report. When multiple devices are connected, they must all be configured for the same age interval, which must be at least twice the length of the query interval, so that missing one report does not stop traffic.
Non-querier age intervals must be the same as the age interval of the querier.
This example configures the MLD group-table age interval to 280 seconds.
Device(config)#ipv6 multicast age-interval 280
