By default, the other querier

robustness variable ] + [
maximum response delay for MLD
general query ] /2.
CAUTION:
To avoid frequent MLD querier changes, set the other querier present interval greater than the MLD
query interval.
To avoid incorrect multicast group member removals, set the MLD query interval greater than the
maximum response delay for MLD general queries.
Configuring MLD fast leave processing
MLD fast leave processing is implemented by MLD snooping. For more information about MLD snooping,
