MLD Snooping Configuration

Configuring Multicast Listening Discovery (MLD) snooping on an IPv6 device consists of the following global and VLAN-specific tasks.

MLD snooping global tasks:

  • Configuring hardware and software resource limits
  • Disabling transmission and receipt of MLD packets on a port
  • Configuring the MLD mode: active or passive (must be enabled for MLD snooping)
  • Modifying the age interval
  • Modifying the interval for query messages (active MLD mode only)
  • Specifying the global MLD version
  • Enabling and disabling report control (rate limiting)
  • Modifying the leave wait time
  • Modifying the mcache age interval
  • Disabling error and warning messages

MLD snooping VLAN-specific tasks:

  • Configuring the MLD mode for the VLAN: active or passive
  • Enabling or disabling MLD snooping for the VLAN
  • Configuring the MLD version for the VLAN
  • Configuring the MLD version for individual ports
  • Configuring static groups
  • Configuring static router ports
  • Disabling proxy activity for a static group
  • Enabling client tracking and the fast leave feature for MLDv2
  • Configuring fast leave for MLDv1
  • Configuring fast-convergence

In this section:

  1. Hardware and Software Resource Limits
    The system supports up to 8,000 hardware-switched multicast streams. The following table shows the MLD snooping resource limits.
  2. Configuring the Hardware and Software Resource Limits
    The following task defines the maximum number of MLD snooping mc mcache entries and the maximum number of multicast group addresses supported.
  3. MLD Snooping Modes
  4. Configuring the MLD Snooping Mode and Version Globally
    MLD mode and version can be configured on RUCKUS devices in global configuration mode.
  5. Configuring MLD Snooping Global Options
    A number of MLD snooping options can be configured on Ruckus devices in global configuration mode.
  6. Configuring MLD Snooping Options for a VLAN
    MLD snooping mode and version can be configured on RUCKUS devices for a specific VLAN.
  7. Disabling MLD Snooping for the VLAN
  8. Configuring the Layer 2 Mode IPv6 Querier Address
    You can configure an IPv6 querier address for every VLAN. This functionality is available only for multicast snooping.
  9. Enabling MLDv2 Membership Tracking and Fast Leave for the VLAN
  10. Configuring Fast Leave for MLDv1
  11. Enabling Fast Convergence
  12. Enabling the Flooding of Unregistered IPv6 Multicast Frames Globally
    The following task enables the flooding of initial packets for unregistered IPv6 multicast groups until hardware entries are programmed. Once the hardware entries are programmed, packets are dropped for unregistered multicast groups.
