A device that sends multicast data to receiver hosts. For example, a video server is a multicast source.
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.
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.
A device that listens to 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.
A multicast user that receives multicast data. A receiver can be a PC, a set top box, or any device with multicast client installed.
The "IPv6 PIM Configuration" chapter describes how to configure IPv6 PIM on a Layer 3 device.
IPv6 PIM is a basic feature of a switch and is not under license control.
All models of S5700 and S6700 series switches support IPv6 PIM.
