Configuring Mld Snooping Querier - HP A8800 Configuration Manual

multicast packets within the VLAN it belongs to and forward then to the host, thus affecting normal
multicast reception of the host.
In addition, the MLD general query and IPv6 PIM hello message sent from the host affects the
•
multicast routing protocol state on Layer 3 devices, such as the MLD querier or DR election, and may
further cause network interruption.
To solve these problems, you can disable the router port from becoming a dynamic router port upon
receiving an MLD general query or IPv6 PIM hello message; thus, network security and control over
multicast users are enhanced.
To disable a port from becoming a dynamic router port:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view or
enter port group view.
3. Disable the port from
becoming a dynamic router
port.
NOTE:
This configuration does not affect the static router port configuration.

Configuring MLD snooping querier

Before configuring MLD snooping querier, complete the following task:
• Enable MLD snooping in the VLAN.
Determine the interval for sending MLD general queries.
•
Determine the MLD last-listener query interval.
•
Determine the maximum response delay 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 run MLD, a multicast router or Layer 3 multicast switch is responsible for
sending MLD general queries periodically, 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 device does not support MLD and it cannot send MLD general queries by
default. In a network where multicast traffic is only switched at the data link layer and no Layer 3 multicast
