The query interval determines how fastMLD Host-Query packets are transmitted on thisinterface.The range forseconds is 0–3600 seconds.ipv6 mld query-max-response-timesecondsConfigure the maximum response time intervalfor the specified interface. It is the maximumquery response time advertised in MLD querieson this interface.The range forseconds is 0–25 seconds.ipv6 mld last-member-query-intervaltenthsofsecondsSet the last member query interval for the MLDinterface, which is the value of the maximumresponse time parameter in the group-specificqueries sent out of this interface.The range is 0–65535 milliseconds.ipv6 mld last-member-query-countcountSet the number of listener-specific queries sentbefore the router assumes that there are no localmembers on the interface.The range forcount is 1–20.CTRL + Z Exit to Privileged EXEC mode.
