Parameters

max-interval-value: Specifies the maximum advertising interval in seconds, in the range of 4 to 1800.

min-interval-value: Specifies the minimum advertising interval in seconds, in the range of 3 to max-interval-value.

The device periodically broadcasts or multicasts an RA at a random interval between the maximum and minimum advertising interval.

The maximum advertising interval cannot be longer than the lifetime of advertised IP addresses. Otherwise, the lifetime is automatically adjusted to a value three times the maximum interval.

# On VLAN-interface 100, set the maximum advertising interval to 500 seconds and the minimum advertising interval to 300 seconds.
