Command: ipv6 mld snooping vlan <vlan-id> immediate-leave
no ipv6 mld snooping vlan <vlan-id> immediate-leave
Function: Enable immediate-leave function of the MLD protocol in specified VLAN; the
―no‖ form of this command disables the immediate-leave function of the MLD protocol
Parameter: <vlan-id> is the id number of specified VLAN, with valid range of <1-4094>.
Command Mode: Global Mode
Default: Disabled by default
Usage Guide: Enabling the immediate-leave function of the MLD protocol will hasten the
process the port leaves one multicast group, in which the specified group query of the
group will not be sent and the port will be directly deleted.
Example: Enable the MLD immediate-leave function on VLAN 100.
Switch (config)#ipv6 mld snooping vlan 100 immediate-leave
22.1.7 ipv6 mld snooping vlan l2-general-querier
Command: ipv6 mld snooping vlan < vlan-id > l2-general-querier
no ipv6 mld snooping vlan < vlan-id > l2-general-querier
Function: Set the VLAN to Level 2 general querier.
Parameter: vlan-id: is the id number of the VLAN, with a valid range of <1-4094>
Command Mode: Global Mode
Default: VLAN is not a MLD Snooping L2 general querier by default.
Usage Guide: It is recommended to configure an L2 general querier on a segment. If
before configure with this command, MLD snooping is not enabled on this VLAN, this
command will no be executed. When disabling the L2 general querier function, MLD
snooping will not be disabled along with it. Main function of this command is sending
general queries periodically to help the switches within this segment learn mrouter port.
Comment: There are three ways to learn mrouter port in MLD Snooping:
1. The port which receives MLD query messages
2. The port which receives multicast protocol packets and support PIM
3. The port statically configured.
Example: Set VLAN 100 to L2 general querier.
Switch (config)# ipv6 mld snooping vlan 100 l2-general-querier
22.1.8 ipv6 mld snooping vlan limit
Command: ipv6 mld snooping vlan < vlan-id > limit {group <g_limit> | source
<s_limit>}
no ipv6 mld snooping vlan < vlan-id > limit
