Configuring MLD Snooping Querier
Configuration Prerequisites
Before configuring MLD snooping querier, complete the following task:
z Enable MLD snooping in the VLAN.
Before configuring MLD snooping querier, prepare the following data:
z MLD general query interval,
z MLD last-member query interval,
z Maximum response time for MLD general queries,
z Source IPv6 address of MLD general queries, and
z Source IPv6 address of MLD multicast-address-specific queries.
Enabling MLD Snooping Querier
In an IPv6 multicast network running MLD, a multicast router or Layer 3 multicast switch is
responsible for sending periodic MLD general queries, so that all Layer 3 multicast devices can
establish and maintain multicast forwarding entries, thus to forward multicast traffic correctly at
the network layer. This router or Layer 3 switch is called MLD querier.
However, a Layer 2 multicast switch does not support MLD, and therefore cannot send MLD
general queries by default. By enabling MLD snooping querier on a Layer 2 switch in a VLAN
where multicast traffic needs to be Layer-2 switched only and no Layer 3 multicast devices are
