Command Information
Parameter Description
query-
interval
Specify the time interval in seconds (1-65535) between general queries sent by the querier. The default value
is 125 seconds.
By varying this value, you can tune the number of MLD messages on the link; larger values cause MLD
queries to be sent less often.
query-
response-
interval
Specify the maximum response delay in deciseconds (1/10 seconds) that can be inserted into the periodic
general queries. The default value is 100 deciseconds.
By varying this value, you can tune the burstiness of MLD messages on the link; larger values make the traffic
less bursty, as node responses are spread out over a larger interval.
NOTE: The number of seconds represented by this value must be less than the query interval.
robustness-
variable
Specify a value between 2 to 10. The default value is 2. The robustness variable allows you to tune for the
expected packet loss on a link. If a link is expected to be lossy, you can increase this value.
NOTE: You must not configure the robustness variable as 0 or 1.
