(config-if)#ipv6 mld immediate-leave
 
group-list 1
Enables the device to remove the group entry from the multicast routing table immediately upon receiving a leave message for the group.
(config-if)# ipv6 mld last-member-query-count 7
Sets the query count used when the software starts up.
(config-if)# ipv6 mld last-member-query-interval 25500
Sets the query interval used when the software starts up.
(config-if)#ipv6 mld limit 100
Configure Max Allowed State on this interface
(config-if)#ipv6 mld querier-timeout
 
300
Sets the querier timeout that the router uses when deciding to take over as the querier.
(config-if)#ipv6 mld query-interval
 
200
Sets the frequency at which the router sends MLD host query messages.

Sets the response time advertised in MLD queries.
(config-if)#ipv6 mld robustness-variable 4
Sets the robustness variable.
(config-if)#ipv6 mld startup-query-count 4
Sets the query count used when the router starts up.
(config-if)# ipv6 mld startup-query-interval 50
Sets the query interval used when the router starts up.
(config-if)#ipv6 mld static-group FF1E::1
