• The default number of MLD general queries the MLDv1/v2 querier sends on startup.
• The number of multicast-address-specific queries the MLDv1 querier sends after receiving an MLD
done message.
• The number of multicast-address-and-source-specific queries the MLDv2 querier sends after
receiving an MLD report that indicates relation changes between IPv6 multicast groups and IPv6
multicast sources.
