Licensing Requirements and Limitations for IPv6 Multicast Route Management

Licensing Requirements and Limitations for IPv6 Multicast Route Management

Involved Network Elements

An IPv6 multicast network consists of the following network elements:
  • Multicast source

    A device that sends multicast data to receiver hosts. For example, a video server is a multicast source.

  • IPv6 Protocol Independent Multicast (PIM) device

    A device that uses the IPv6 PIM protocol to generate and maintain multicast routing entries and forwards multicast data based on multicast routing entries. On an IPv6 multicast network, all Layer 3 devices must run IPv6 PIM; otherwise, multicast forwarding paths cannot be established.

  • MLD querier

    A device that exchanges MLD messages with receiver hosts to create and maintain group memberships. On a multicast network, Layer 3 devices connected to network segments of receivers must run the MLD protocol or be configured with static MLD groups. Otherwise, upstream PIM devices cannot know the multicast groups that users want to join, and therefore cannot establish multicast forwarding paths.

  • MLD snooping device

    A device that listens on MLD messages exchanged between upstream Layer 3 multicast devices and receiver hosts to create and maintain Layer 2 multicast forwarding entries, which are used for accurate multicast data forwarding on a Layer 2 network. To prevent broadcasting of multicast packets on a Layer 2 network and conserve network bandwidth, it is recommended that you configure MLD snooping on Layer 2 devices.

  • Receiver

    A multicast user that receives multicast data. A receiver can be a PC, a set top box, or any device with multicast client installed.

Generally, IPv6 multicast route management is configured on a device running IPv6 PIM to monitor and maintain multicast forwarding paths.

Licensing Requirements

IPv6 multicast route management can be configured after IPv6 is enabled, whereas the IPv6 feature requires a license.

For details about how to apply for a license, see S Series Switch License Use Guide.

Feature Limitations

  • V200R005 and later versions support IPv6 multicast route management configuration on physical interfaces that have been switched to Layer 3 mode using the undo portswitch command.
  • Before configuring IPv6 multicast route management, enable IPv6.
