Configuring MLD
Parameter
Startup query interval
Startup query count
Robustness value
Querier timeout
Query max response time
Query interval
Last member query response interval
Description
Startup query interval. By default, this interval is
shorter than the query interval so that the software
can establish the group state as quickly as possible.
Values range from 1 to 18,000 seconds. The default
is 30 seconds.
Number of queries sent at startup that are separated
by the startup query interval. Values range from 1 to
10. The default is 2.
Robustness variable that you can tune to reflect
expected packet loss on a congested network. You
can increase the robustness variable to increase the
number of times that packets are resent. Values range
from 1 to 7. The default is 2.
Number of seconds that the software waits after the
previous querier has stopped querying and before it
takes over as the querier. Values range from 1 to
65,535 seconds. The default is 255 seconds.
Maximum response time advertised in MLD queries.
You can tune the burstiness of MLD messages on the
network by setting a larger value so that host
responses are spread out over a longer time. This value
must be less than the query interval. Values range
from 1 to 25 seconds. The default is 10 seconds.
Frequency at which the software sends MLD host
query messages. You can tune the number of MLD
messages on the network by setting a larger value so
that the software sends MLD queries less often.
Values range from 1 to 18,000 seconds. The default
is 125 seconds.
Query interval for response to an MLD query that the
software sends after receiving a host leave message
from the last known active host on the subnet. If no
reports are received in the interval, the group state is
deleted. You can use this value to tune how quickly
the software stops transmitting on the subnet. The
software can detect the loss of the last member of a
group or source more quickly when the values are
smaller. Values range from 1 to 25 seconds. The
default is 1 second.
