MLD

Introduction

Multicast Listener Discovery Protocol (MLD) establishes and maintains the IPv6 multicast group memberships between a Layer 3 multicast device and the hosts on the directly connected subnet.

MLD has the following versions:

• MLDv1—Derived from IGMPv2, MLDv1 manages IPv6 multicast group memberships based on the query and response mechanism.

• MLDv2—Derived from IGMPv3 and backwards-compatible with MLDv1, MLDv2 provides hosts with enhanced control capabilities and enhances the MLD state.

After MLD is enabled on an interface, the interface can establish and maintain IPv6 multicast group memberships.

vSystem support information

Support of non-default vSystems for this feature depends on the device model. This feature is available on the Web interface only if it is supported.

Configure MLD

Prerequisites

Complete the following tasks before you configure this feature:

• Assign IP addresses to interfaces on the Network > Interface Configuration > Interfaces page.

• Configure routes on the Network > Routing page. Make sure the routes are available.

• Create security zones on the Network > Security Zones page.

• Add interfaces to security zones. You can add interfaces to a security zone on the Security Zones page or select a security zone for an interface on the Interfaces page.

• Configure security policies to permit the target traffic on the Policies > Security Policies page.

Procedure

1. Select Network > IP Multicast > MLD.

2. Click Enable MLD on interfaces, and then enable MLD on the interfaces as needed.
