Enabling Fast-Leave Processing; Configuring Mld Ssm Mappings - HP FlexFabric 5950 series Configuration Manual

3. Set the MLD querier's
robustness variable.
4. Set the MLD startup query
interval.
5. Set the MLD startup query
count.
6. Set the MLD general query
interval.
7. Set the MLD last listener
query interval.
8. Set the MLD last listener
query count.
9. Set the maximum response
time for MLD general
queries.
10. Set the MLD other querier
present timer.

Enabling fast-leave processing

This feature enables an MLD querier to send leave notifications to the upstream without sending
multicast-address-specific or multicast-address-and-source-specific queries after receiving a done
message. Use this feature to reduce leave latency and to preserve the network bandwidth.
To enable fast-leave processing:
Step
1. Enter system view.
2. Enter interface view.
3. Enable fast-leave
processing.

Configuring MLD SSM mappings

This feature enables the device to provide SSM services for MLDv1 hosts.
This feature does not process MLDv2 messages. Enable MLDv2 on the receiver-side interface to
ensure that MLDv2 reports from MLDv2 receiver hosts can be processed.

By default, the MLD querier's
robustness variable is 2.
By default, the MLD startup query
interval equals one quarter of the
MLD general query interval.
By default, the MLD startup query
count equals the MLD querier's
robustness variable.
By default, the MLD general query
interval is 125 seconds.
By default, the MLD last listener
query interval is 1 second.
By default, the MLD last listener
query count equals the MLD
querier's robustness variable.
By default, the maximum
response time for MLD general
queries is 10 seconds.
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.
