Configuring MLD snooping querier

Configuration prerequisites

Before you configure MLD snooping querier, complete the following tasks:
Enable MLD snooping in the VLAN
•
Determine the MLD general query interval
•
Determine the MLD last-member query interval
•
Determine the maximum response time for MLD general queries
•
Determine the source IPv6 address of MLD general queries
•
Determine the source IPv6 address of MLD multicast-address-specific queries
•

Enabling MLD snooping querier

In an IPv6 multicast network that runs MLD, a multicast router or Layer 3 multicast switch sends MLD
queries, so that all Layer 3 multicast devices can establish and maintain multicast forwarding entries, in
order to forward multicast traffic correctly at the network layer. This router or Layer 3 switch is called the
"MLD querier."
However, a Layer 2 multicast switch does not support MLD. Therefore, it cannot send MLD general
queries by default. When you enable MLD snooping querier on a Layer 2 switch in a VLAN where
multicast traffic is switched only at Layer 2 and no Layer 3 multicast devices are present, the Layer 2
switch sends MLD queries, so that multicast forwarding entries can be created and maintained at the
data link layer.
Follow these steps to enable the MLD snooping querier:
To do...
Enter system view
Enter VLAN view
Enable the MLD snooping querier
Use the command...
system-view
interface interface-type interface-number
port-group manual port-group-name
mld-snooping router-port-deny [ vlan
vlan-list ]
Use the command...
system-view
vlan vlan-id
