Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command displays MLD information for interfaces on the public network.

interface-type interface-number: Specifies an interface by its type and number. If you do not specify an interface, this command displays MLD information for all interfaces.

proxy: Displays the MLD proxy interface information. If you do not specify this keyword, the command displays MLD information for all interfaces.

verbose: Displays detailed MLD information.

Table 113: Command output

Field	Description
Vlan-interface1(FE80::200:AFF:FE01:101)	Interface and its IPv6 link-local address.
MLD is enabled	MLD is enabled on the interface.
MLD version	Version of MLD that the interface runs.
Query interval for MLD	MLD query interval, in seconds.
Other querier present time for MLD	MLD other querier present interval, in seconds.
Maximum query response time for MLD	Maximum response time for MLD general query messages, in seconds.
Last listener query interval	Interval for sending MLD multicast-address-specific queries or MLD multicast-address-and-source-specific queries, in seconds.
Last listener query count	Number of MLD multicast-address-specific queries or MLD multicast-address-and-source-specific queries sent for the group.
Startup query interval	MLD startup query interval, in seconds.
Startup query count	Number of MLD general queries sent on startup.
General query timer expiry	Remaining time for the MLD general query timer. This field displays Off if the timer is disabled.
Querier for MLD	IPv6 link-local address of the MLD querier.
MLD activity: 1 join(s), 0 done(s)	MLD activity statistics: join(s)—Total number of IPv6 multicast groups that the interface has joined. done(s)—Total number of IPv6 multicast groups that the interface has left.
IPv6 multicast routing on this interface	Whether IPv6 multicast routing is enabled: Enabled or Disabled.
Robustness	Robustness variable of the MLD querier.
Require-router-alert	Whether the feature of dropping MLD messages without Router-Alert is enabled: Enabled or Disabled.
Fast-leave	Whether fast-leave processing is enabled: Enabled or Disabled.
Startup-query	Whether the MLD querier sends MLD general queries at the startup query interval on startup: On—The MLD querier performs the above action. Off—The MLD querier does not perform the above action.
Other-querier-present-timer-expiry	Remaining time for MLD other querier present timer. This field displays Off if the timer is disabled.
MLD groups reported in total	Total number of IPv6 multicast groups that the interface has joined dynamically. This field is not displayed if the interface does not join IPv6 multicast groups.
MLD proxy is enabled	MLD proxying is enabled.
Version1-querier-present-timer-expiry	Remaining time for the MLDv1 querier present timer. This field displays Off if the timer is disabled.
