11 MLD Snooping Configuration
About This Chapter
This chapter describes the implementation and configuration procedures of Multicast Listener
Discovery (MLD) snooping on the S7700.
11.1 Overview of MLD Snooping
When MLD snooping is enabled, the S7700 creates a Layer 2 forwarding table for multicast
data packets by listening to MLD messages. In this manner, the S7700 manages and controls
the forwarding of multicast data packets to ensure that these packets are sent only to the hosts
that need the multicast data.
11.2 MLD Snooping Features Supported by the S7700
This section describes the MLD snooping features supported by the S7700.
11.3 Enabling MLD Snooping
This section describes how to enable MLD snooping, add an interface to a multicast group
statically, and configure an interface as a static router interface.
11.4 Configuring a Multicast Group Policy for a VLAN
This section describes how to configure a multicast group policy for a VLAN.
11.5 Configuring Prompt Leave of Interfaces
This section describes how to configure prompt leave of interfaces in a VLAN.
11.6 Configuring the MLD Snooping Querier
This section describes how to configure the MLD snooping querier.
11.7 (Optional) Modifying Parameters of MLD Snooping
This section describes how to optimize the performance of MLD snooping by modifying MLD
snooping parameters, including the aging time of the router interface, interval for sending Last
Member Query messages, interval for sending the General Query messages, maximum response
time for MLD messages, MLD robustness variable, source IP address of the MLD message sent
to respond to changes of Layer 2 network topology, MLD version, duration for suppressing the
same Report messages, maximum number of MLD snooping entries, and whether the Router
Alert option is contained in MLD messages.
11.8 Maintaining MLD Snooping
This section describes how to maintain MLD snooping.
