HP FlexNetwork MSR 954 User Manual

•
You can configure the MLD query and response parameters globally for all interfaces in MLD
view or for an interface in interface view. For an interface, the interface-specific configuration
takes priority over the global configuration.
•
To avoid frequent MLD querier changes, set the MLD other querier present timer greater than
the MLD general query interval. In addition, configure the same MLD other querier present timer
for all MLD routers on the same subnet.
•
To speed up the response to MLD queries and avoid simultaneous timer expirations that cause
MLD report traffic bursts, you must set an appropriate maximum response time.
 For MLD general queries, the maximum response time is set by the max-response-time
command.
 For MLD multicast-address-specific queries or MLD multicast-address-and-source-specific
queries, the maximum response time equals the MLD last listener query interval.

3.
Set the MLD querier's
robustness variable.
robust-count
count
By default, the MLD querier's
robustness variable is 2.
4. Set
the MLD startup query
interval.
startup-query-interval
interval
By default, the MLD startup query
interval equals one quarter of the
MLD general query interval.
5.
Set the MLD startup query
count.
startup-query-count
count
By default, the MLD startup query
count equals the MLD querier's
robustness variable.
6.
Set the MLD general query
interval.
query-interval
interval
By default, the MLD general query
interval is 125 seconds.
7.
Set the MLD last listener
query interval.
last-listener-query-interval
interval
By default, the MLD last listener
query interval is 1 second.
8.
Set the MLD last listener
query count.
last-listener-query-count
count
By default, the MLD last listener
query count equals the MLD
querier's robustness variable.
9. Set the maximum response
time for MLD general
queries.
max-response-time
time
By default, the maximum
response time for MLD general
queries is 10 seconds.
10.
Set the MLD other querier
present timer.
other-querier-present-timeout
time
By default, the MLD other querier
present timer is
calculated by
using the following formula:
[ MLD general query interval ] ×
[ MLD robustness variable ] +
[ maximum response time for
MLD general queries ] / 2.
