ipv6 mld snooping query-interval

Sets the interval between MLD snooping queries for a VLAN or a bridge domain.

Syntax

ipv6 mld snooping query-interval interval

no ipv6 mld snooping query-interval

Command Default

By default, the interval is 125 seconds.

Parameters

interval: Valid intervals range from 1 second to 1800 seconds.

Modes

VLAN or bridge domain configuration mode

Usage Guidelines

The no ipv6 mld snooping query-interval form of the command restores the default interval of 125 seconds.

In any given subnet, one multicast router is elected to act as an MLD querier. The MLD querier sends out the following types of queries to hosts, at the interval you set.

Multicast Listener General query: (MLD v1, v2) Asks whether any host is listening to any group.
Multicast Listener Group-specific query: (MLD v1, v2) Asks whether any host is listening to a specific multicast group. This query is sent in response to a host leaving the multicast group. The router can quickly determine whether any remaining hosts are interested in the group.
Multicast Listener Group-and-source-specific query: (MLD v2) Asks whether any host is listening to group multicast traffic from a specific multicast source. This query is sent in response to a host indicating that it is not interested in receiving group-specific multicast traffic from the multicast source. The router can quickly determine whether any remaining hosts are interested in receiving group multicast traffic from that source.

Examples

The following example configures the interval for a VLAN.

device# configure terminal
device(config)# vlan 10
device(config-vlan-10)#ipv6 mld snooping query-interval ?
Possible completions:
	<1-18000>    Query Interval value (Default: 125 s)
device(config-vlan-10)# ipv6 mld snooping query-interval 500

The following example configures the interval for a bridge domain.

device# configure terminal
device(config)# bridge-domain 10
device(config-bridge-domain-10)#ipv6 mld snooping query-interval ?
Possible completions:
	<1-18000>    Query Interval value (Default: 125 s)
device(config-bridge-domain-10)# ipv6 mld snooping query-interval 600
